TEA stg3 vs ETP 215's... thoughts? I've been searching for the last hour or so, and have come up with very little info on the subject, mostly from the TEA side of things.
Anyhow, i'm looking at upgrading my combo this winter. Currently i've got a Tr224 (114) cam, and TEA 1.5' 5.3 heads, with an ls6 intake. I'm planning on moving up to a mid 230's duration cam with lift at or around .600". Also planning on a 90/90 combo. This will all be with stock cubes btw, pistons are flycut.
I really like my heads now, but i'm thinking i could stand to gain quite a bit by going bigger. I've been looking at TEA's Stg 3 head (5.3 version) and i like what i see. However i can't read through a post about heads on this board without hearing about the awesome-ness of ETP's 215 heads. Looking at the flow numbers, the nod goes to TEA, by quite a bit, especially on the exhuast side, but i know flow numbers don't mean everything.
Back before my ls1 days, i've built a couple SBC's, utilizing the big head/ small cam theory. Both were very successful, and made gobs of power at pretty much any point in the rpm band. I'd like to shoot for the same kind of result here. For reference, i'm looking to hit the 480rwhp mark, and i'd like to see a pretty fat torque curve that spends the majority of it's time over the 400ftlb mark.
thoughts, opinions?

From what I've seen on this board, the TEA Stage III heads make good power, but have large cross-sectional runners. ETP 215s and AFR 205/225s have the same if not better airflow as the TEA Stage 3s, but the air speed with the ETP/AFR heads is going to be so much higher (because of much smaller cross-sectional area), they will make more power across a wider range of rpm (think area under the curve).

i know i can, but the "right" cam for that situation will be more wild than i'm looking for. I've done the wild cam thing before, and i wasn't happy with it. Thats why i'm trying to accomplish a small cam/big head combo.
I guess the big question is will the 480 mark be attainable with the cam i'm going with and the TEA heads. If so, i'm going with them, since they're much cheaper. Theres also a chance that i may be able to have my heads worked to stg 3 specs, which should save me a couple more bucks. If it doesn't seem like it'll happen, i'll spend the extra dough on the etp heads.
