Default low compression no FI ???

figured id post this here since people in this section might have some experience in this situation. Ok heres the deal i have the epps FI cam (232-240 115lsa) and lq9 stage III heads 72cc combustion chambers that are about ready to be installed as i plan on doing procharger later on once i can save up enough, my question is i know this is going to lower my compression so am i going to gain power at all with this h/c set up vs stock or am i going to loose power since it will lower my cr? seeing as it might be a little while till i can save up for the procharger i would like to know if im going to gain anything from this or loose anything. thank you for any input.

you will loose power because you lowered your CR, but you should be able to gain some with the new heads. but i think it will work out that you loose a little bit of power. if you have an ls1 your cr will be around 9.5:1 instead of 10.25:1 with the 72 cc heads.

I would guess that you would loose a bit of low end torque, but gain hp on top.

You should pick up a nice bit of hp up top vs. stock heads and cam even with the drop in compression.
