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

Chris Ja

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.

dj haf

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.

Max 93

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.

Max 93

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

KagA152

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

aklim

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.

grygst76

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.

Max 93

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.

formularpm

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.
