If the heads are not milled.. 64cc / stock MLS GM headgaskets , wouldn't that put the compression closer to 10.5:1 ?

10.65, 11:1 would require 61.4 cc chambers or thinner gaskets (64cc and .040)

Mikey, have you guys ever run this combo with a set or afr 205 heads? If so what kind of dyno #s has it put down? Very interested bc I'm thinking of an upgrade from my 228/228 cam. Thanks

I'd be willing to bet you would fall 15-25 rwhp short of Mikey's numbers depending on your setup. Those TFS 215s seem to be whooping *** on our AFR 205's.

Not trying to be reasonable, but my combo was supposed to make 500 rwhp all day long. Best unrepeated pull was 492/455. Consistently put down 490/445. The TFS 215's just seem to make more power, especially up top.

BTW I'd love to see how my car would respond to the TFS 215's. If she picked up 15rwhp from the swap I'd be speechless.

Now predator come on, you totally missed the point. So many well thought out combos have been put together. Of those that were very similar with the only difference being heads (afr 205 vs tfs 215) it seems that the additional flow of the larger runner has helped the combo make more power everywhere. Ideally it would be nice to see a back to back comparison between the two heads. Don't care what cam, exhaust etc etc you use as long as it the same for afr's and tfs heads. Seeing all the results I'd put my money on the TFS. Awesome peak power, and good power under the curve as well. JMO even though I am an AFR 205 owner.

One more question to Predator, why do you think my combo wouldn't make more power with a set of TFS 215's ??

I would yank them and go TFS. I cant sleep knowing there is that much power to be had. There is another member on SVT with a C5Z and he is turning 10.20's @133+ traps n/a with TFS heads. Im considering a few choices but as far as heads go it will be TFS.

is that 10 rwhp worth over $1K to you?
As you said back to back on same day, because i've seen 500rwhp from a AFR 205s, so they can both do it. But to say they kick AFR ***, that is presenptuous don't you think?

read this again and explain where it kicks ***
https://ls1tech.com/forums/generation-iii-internal-engine/732392-recipe-500-rwhp-heads-cam.html

508rwhp, 205 cc 300 cfm @ .600, 238 duration cam,

does combo ring a bell?

BTW Mickey, nice combo

I wouldn't write off the AFR 205s as being a step below the Trick Flows. A member on this board, 00T/A has a badass set of TFS 215s, a Vengeance ported FAST 92, and the same cam as in this build. His TA is in the 440 rwhp range. Funny thing those dynos. Similar parts, same heads, yet lower numbers. Some dynos spit out better numbers than others. Some combos go together better than others.
