which heads???

Was just looking in Summit and tyring to decide what heads are better. The Dart Iron Eagle or the Pro Lightining. They both have 64cc chambers and 180cc runners. They will be going on a 350 with a Holley Stealth Ram and a cam that has yet to be decided on ( open to thought an that too). Any thoughts

AFR's... 190 or 195

AFR 210 if you are looking to make some big power. They are mad for the L98 motor and will wake up that sleeping beauty. Just my . 02

Talk to the people at AFR. Tell them what you are trying to do and what you have. They will tell you what you need.

wouldnt 210's be too big for a 350?

and yeah, you should call AFR, they'll tell you what type of heads would give you awesome power, and they'd probably also tell you what cam goes good with their heads

I didn't see AFR's as a choice there guys, but if he had the money sure. I like the Pro lightning heads better than the Iron Eagles just from everything I have read about them, I compared all heads awhile back and I bought some Pro Action Vortecs as the best bang for the buck and they look like very well made castings with very good machine work.

I agree with you guys on AFR heads. I have a set on my 383 LT1. But I am working on putting together a heads, cam, intake combo for my friends car and money is an issue. The AFR's are $500 more.

Don't you have to use a differant intake with the Vortec heads?

yes, youd have to get a different intake if you use vortec heads because the runner is taller, but since youre getting an intake anyway, if you can get a deal on the vortecs & intake, go for it. otherwise i would go with the pro topline heads, and convert a LT1 intake, port it some too

If you want to use the TPI setup you will have to get the Scoggy Dickin intake manifold. That is the only vendor at this time which is why I don't like the vortec heads.

How about matching the cam specs to the heads and the rest of your setup? before you choose the heads consider the stealth as just the topper to your combo, choose a cam that matches the stealths range, then choose the heads that match the cam and the intake, then you will make mad power

I disagree, I think you should always choose the cam last. I guess its personal preference, though. If you can afford the AFRs they are the way to go, if not, the ProToplines will perform great and should be your #1 choice. A great street combo would be HSR, 180cc Lightnings, and an XR276HR Comp roller. With full exhaust and a proper tune 400-420hp shouldnt be hard to attain.

Thats ppretty much the combo I had in mind. He does have headers and cat back, upgraded trans with a mild stall and 3.73's that have yet to be installed. Is this combo good for high 12's ? That is his main goal.

AFR heads all the way. Yea AFRs are way out there in price But you know what? They are made for racing. & they are just being made low enough power for those of us that dont have big racing cars or the money to do that. AFR has been around almost longer than Summit & Jegs but have been making stuff for PRO drivers. John force & those guys.

He said money was an issue, so the AFRs obviously arent an option. Besides, the Lightnings flow just as well as the AFRs, the only disadvantage they have is a slightly larger port volume, and its really only a disadvantage at lower rpms. I think the extra cost of the AFRs more than offsets this, and the Toplines are a much better deal and just as good of a head.

HSR, 180cc Lightnings, and an XR276HR Comp roller. With full exhaust , would 24# injectors be good for this combo?

for the 383? Yes.

for the 350

For a 350, you might run a little rich as they came with 22 pph. Nothing a little EPROM reprogramming won't fix

I thought 91 Z's came with 18#. would 22# work better? He will be getting a custom chip also when the engine is put back together

305 came with 19 pph and 350 came with 22 pph. Who is doing the custom chip? Make sure they make adjustments for it. Also make sure they fine tune it and not just give you one that they burnt. Mine was refined 2 times before I was happy.

so do you think stock injectors are big enough for this combo?

24 pph will be just fine. Either way you go, you need a custom chip to maximize the car. I would go 24 just to be safe. Who is doing the chip and will they take readings and make adjustments or will they just burn you one and tell you it is fine? When I went to LPE, they took quite a few hours and a few burns to get it nuts on.

Not sure who is going to burn the chip yet. either PCMforless or I know a local guy that can do it.

I am also trying to reach 12 seconds, I am trying to do it N/A. I want to get the stealth ram but I don't want to get aluminum heads. Is there a huge difference between aluminum and cast iron other than the weight? i was thinkin somewhere around 190cc heads,the stealth ram, a 58mm TB,and i already have the 24lb injectors. The thing i really need right now is a new rear. I have a 2.73 open rear which is holding me up pretty bad, and I have stock 305 heads. those 2 things and i think i could be in the lower 13's. But thats a whole nother story.

anyway, I heard good things about both sets of heads. I would read as much as you can about them, get a lot of advise from other people and then try to decide. My friend has dart heads on his 383 and his loves them. I am going to pick either Dart,AFR,or Pro topline. I hear good things about all of them. And I'm not made of money so I would probably go for (as I always hear) "The best bang for the buck". I wish you luck finding the set of heads you want! Hopefully we could both see the 12's.

Don't waste your money on a 58mm TB. you don't need it, 52 at the most unless your making serious power. Also I see in your sig that you are running a performance cam, mind sharing what it is?

This is how i weirdly ended up with a great deal. The person i bought my car from bought it for $3000 about 3 months before I bought it. the kid he bought it from swapped the motor and did a bunch of stuff to it. Then the kid i bought it from started having problems with it. He replaced all the sensors and was workin on the car for about a month. He thought the computer went. And i guess he just got tired of working on it, so who bought this kid's mustang. And in class one day he just asked anyone if they wanted to buy his car for $500. So I went home at lunch, got the money, beat someone else to it and now i have a great car. It ended up needing a new distributor and coil. I got the car with the rebuilt motor in it and i know very little so far, I know it was just freshly bored 30 over. It had a cam put it in. It has a forged crank that is 2 sizes over stock. And that it still has the orignal 305 heads. I just recently got the guys number who did the motor work and I am going to contact him ASAP.

Anyone can do it. Not anyone can do it well. I had 2 chip burners and both of them did good work. Lingenfelter and www.fasterproms.com both had to burn it and reburn it and reburn it till it was dead on. Anything else is not custom.

I am having the local guy burn the chip for my 93 with the 383. he said he will hook up a wide band o2 sensor and hook his laptop the the PCM and we will drive around for a while so he can get all the info he needs to make my chip. This guy really knows what he is doing, he has a 95 TA with 600 RWHP and passes emisions.

I was meaning if Money wasnt an issue.

aklim, someone told me that since my car is SD (1990), i cant change to a higher # fuel injector.... that i'd have to convert my car over to MAF.... the kid who told me this owns a mustang, and he had to do it, but i just wanted to know if it goes the same with camaros

That can't be true, because I have a 90 iroc with speed density and i put 24 lb. injectors in and i don't have any problems, except my idle went up a little bit, but when i get my chip burned that problem will be solved.

DJ, that kid is on drugs. You can change. Since it is SD, it is not as adaptable but you can with an EPROM burn which you will want anyway since you are doing other mods to it. SD is not as adaptable as MAF but it is a pain to switch.

thanks for cleaing that up for me :) i was thinking that tuning would be the key to everything i do to my car, and when my friend told me about what he had to do to his stang, i was like "i think if i want to run bigger injectors, all i have to do is reprogram the eprom and im set"
