Here ya go. These are the numbers off the actual flow sheet that was packaged with the heads. Also a link to the thread on LS1tech.


Lift Intake Exhaust
.200 140.4 118.5
.300 219 180.4
.400 260.4 231.4
.500 301.4 254.3
.550 319.9 260.8
.600 332.1 264.2

If these numbers aren't sufficient, I can scan and post the original paperwork and receipts from TEA, just ask. FWIW, a couple of other buyers of these heads published their results, which were slightly lower, but almost identical on the exhaust side (if I remember correctly). TEA told me they had refined their porting a little bit since their first sets.

You might consider getting independent flow numbers...

The numbers you are quoting are from the manufacturer and are NOT from a SuperFlow style bench. It's like comparing DynoJet #'s to Mustang #'s on a dyno....not comparable information.

I believe they use a Flow Data bench and their exhaust flow is especially high when compared to a SuperFlow (30+ CFM's).

These heads may or may not set the bar higher, but dont base your reasoning that they will on the numbers (flowdata) you have in hand. Independent flow testing and independent dyno tests on the average Joe build-ups will ultimately be the real test to see where these heads belong in the current LSx ever growing list of options.

Hope this sheds some light on things...

Which is why I repeatedly said time will tell, and there's not enough of these new heads out there yet to get a reliable sampling, etc.. Regarding the numbers, there's variables in every flow bench, even of the exact same model, like the difference in Dynos, some of which are sizable. However, TEA has been in the porting business long enough to develop a very good reputation, and I trust their integrity, and experience. No knock on your heads, Tony, I think they're a great performing, quality product. I just think they have been eclipsed, as all things are, by a new design. Once again, time will tell.

Here is another reason to buy AFR. CARB legal. I believe that's what Tony Mamo said to me?

What size intake runners and what bore are these numbers for?

215cc intake runners, and on a 3.90" (std.) bore. They also are making a 225 head for the bigger bores.

bobbss, the RHS heads you have came from ETP, so the heads are actually ETP heads. I would bet money that the ETP's exhaust numbers are as good or better than the new TEA Trickflow heads.

Remember, TEA is using an Flowdata bench which inflates the numbers on the intake (15-20) and the exhaust(30+). The numbers you have from RHS are on a superflow bench which read lower than TEA's bench.

Read Tony's quote from above.

There is a proven combo of the AFR heads and their cam, not sure on emissions though or how it does in CA. Tony could answer that. I have the Darts, which are a good alternative if on a budget. With the AFR head/cam setup, I think your goal is achievable and proven by quite a few.

I'm not going to use nitrous, and when I can I think I will just port the ls6 stock heads on the z. I can use the savings on other mods.

If i had money stacked up like cordwood I would probably buy afrs or some similar product.
