How do you get in touch with Lloyd to buy his heads??

I am sure that the TEA LS1 heads that you are talking about are a NICE head just like the LT1 heads. The LT1 heads that TEA produces are VERY nice. Much nicer than other heads that cost hundreds more. They are a CNC head and I do not think that you could get a better CNC head unles ya want to weld on half of the sets. Since it is a CNC's head there are some places that need to be left thick for core shift and other casting differences. They have a GREAT flowing valve job and flow good #'s at all lifts.

1 reason Black95Form wanted more work done is because he was expcting flow #'s closer to what was advertised (270/239) and he was expecting these #'s to be comparable to #'s from a Superflow bench.

It seems pretty well known that GTP heads flow about 250-255 on a Superflow bench and he was expecting 270 from the same bench. When the TEA head flowed 255 as well he was a lil depressed. The low/mid lift #'s on the intake port are MUCH better than the GTP head though. If the head was advertised as a 255 cfm head with KILLER low/mid lift flow #'s than he would have been happy with these #'s. He was expecting the 270 cfm AND the low/ mid lift #'s that they have.

Another reason is because the extra CFM was just sitting there and easily obtained. It was obtained while not touching the shortside or valve job. Mainly by removing about 3 cc's worth from the long wall, narrowing guide and pushrod wall. Easily picked up cfm, not much runner volume added, did not cost much, no loss of ANY low or mid lift flow. How could he resist. He could have ran the heads like they were but he wanted what was advertised.

Will they make more power now than before ?? who knows.
Will the car be any faster?? who knows.
He is happy now and that is all that matters.
FWIW I can't see the extra CFM and 3 cc's of runner volume HURTING his 383.

FWIW the TEA heads and their flow #'s (at all lift points) would be hard to beat for the money ($1500 or less I think).
Almost anyones head could be touched up and nit-picked for extra cfm. It is a CNC head so that makes it a lil easier and if ya ask Brian at TEA he could posibly do this for a few extra $$$.

I just wanted to let people know that he is not being picky or racing a flow bench. He now realizes that flowbenches vary and like I mentioned, the extra CFM was inexpensive, easily obtained and did not hurt flow anywhere.

I also wanted to let people know that I am not bashing TEA.
TEA heads are NICER than almost everything else out there and have KILLER low/mid lift #'s and I am sure they would have made good power untouched.

Nighttrain66,

Well put. I am not out to put anyone out of business. I originally posted this to see if the advanced gurus would go after more cfm in the head for my stroker build up. I have learned alot about the difference from a cnc to a hand port job, and flow bench results. My heads have been flowed on 4 different benches and I have 4 different results.

O.k. got to the flowbench. Since I sell TEA's stuff I wanted to double check them. I don't want to sell stuff that is not up to snuff around here, it's not just their name then it's mine.

For the LT4 heads that I have from TEA. They have stock valves in them and were angle milled to get a VERY small chamber. Now just to preface this, angle milling does not improve flow. It is the only way to keep out of the valve seats when you want a small chamber. It does change the valve angle, which might get it in the 21-22 deg range. The head ports are not changed to go along with this flow so it's not going to help really, the short side might have less shrouding but the plug side of the chamber is about the same. Either way, most heads I have seen that were milled flowed less and not more due to the importance of the chamber.

This is only intake because I don't have a pipe for these heads, so I'm not going to compare apples to oranges. Since the intake was really the ports in question (and the one that makes the power) that's what I wanted to verifiy.

Numbers quoted to me by TEA:

.200 143
.300 205
.400 247
.500 280
.550 288
.600 290

Numbers I found on a SF-600 Bench, with a clayed inlet:

.200 147
.300 207
.400 252
.500 279
.550 285
.600 298

Now I don't know about you but that's pretty dam close to what they said. Neither Chris (his bench)nor I did any flow bench tricks to pull this off. We put them on the bench and checked the flow. These heads did have the tool marks sanded off, but there was no marks that showed anything different from that.

Now I double checked a set of Brodix T1's from Weld Tech. They had the tool marks from the CNC on them and had no hand finishing. They had the same results that Weld said they would just like the TEA LT4's. One thing about CNC ports is that they are usually close like they say they are. Funny they were also 290cfm heads and 215cc's, except alot better flowing in the mid lift numbers. (267 @ .400) Also a 2.08" valve vs a 2.00" valve.

I've spoken with Lloyd about the ones he re-worked and his post above states all of what we talked about. I still want to double check a set of LT1's from TEA.

Obviously something odd happened with Black95Form's heads. Either way now they are going to be killer LT1 heads. On top of that still below GTP's price and it will outflow them too.

The LT4 heads are going onto 96z's 383, which I would guess will be in the 450rwhp range. More if I could get some better flow thru the intake, or using a single plane. The flow thru the intake was hurt from .400 and up at about the rate of 10%. The intake was ported for a certain size port working more on tuning, I wish I could cut it open and find some more flow in it but that's probably not going to happen. Either way it's even more evidence that a single plane conversion is needed for a LT1-4 engine. Since before the T1's flowed only 2% less with the Super Vic on.

So basically I'll keep using TEA's heads. I want to figure out why the LT1 porting is not consistent, but with a little help they are definately Bad A$$ stock ported heads.

That's my thoughts.

Hi,
Could someone explain this single plain intake conversion you guys mentioned, I am not sure how it would work.
I thought all single plain manifolds where carbed?
Thanks!
Chris...

 

Yeah, all single plane intakes are carbed. Unless you're talking about one of the Edelbrock/Accel type manifolds built for use with a 4bbl throttle body. Those were built specifically for that purpose (dry flow).
What Bret is speaking about is using a single plane carb intake, welding in the injector bungs and using a 4bbl throttle body or maybe even an "L" and the LS1-type tb. So basically we're talking about using a HVH Brodix, Vic. Jr, Team G, etc., to get a longer runner. Thought about going that route with my build but didn't.

The LT4 intake I'm using doesn't pose to be a restriction based on the flow we saw, intake and tb. Did require a bit of internal work on in the plenum, lots of radiusing and then the intake has to be patched back up. Nothing too crazy when you consider that guys have been cutting access holes in manifolds for a long time. Seems to work fine.

That should be the quote of the day.

As Bret mentioned the LT4 heads he is talking about is going on my 383. I am very happy with my heads as they are and the flow numbers Bret got seemed to reinforce this even more. FWIW my GTP LT1 heads flowed 40cfm less than the TEA LT4s did. And for what they cost compared to the GTP's there is NO comparison.
