any idea on this common setup?

how much HP to expect?

TR 224/224 .563/.563 112 LSA
prc stage 1 ls6 heads
hardened pushrods, dual springs, tit retainers
kooks 1 3/4 LT's catted H pipe
ls6 intake with egr prov.
ported & polished tb
fipk k&n with ultra Z hood.

(NOW how much would i loose if i just stuck with the stock 853 heads and just ported n polished them??)

these are my plans for my 99 z/28 m6
any other suggestions?

Without the heads I would say about 390 rwhp but I would port and polish 853s...if anything find some 241s and port them...all you really need is ported. They wont make as much as the LS6s but if you plan your compression and either mill the heads or use thinner gaskets you could still make great numbers.

Low 400's with the stage 1 heads shouldn't be too hard. Good luck!

i would say close to the 400range. most 224 cams i see usually make 365-375ish..some have hit close to 390.

Heads are going to kill you. Cam only with that set up & slowhawk tune, I made 38Xrwhp/370rwtq. After AFR's & Don's magic touch, 430rwhp/403rwtq.

But like Don said, depends on how much rwhp you are making now. I would guess at 400rwhp/370rwtq with the PRC heads
