what gains going with stock 243's? on my LS1, i plan on replacing the heads and found a set of 243's. how much should i expect to gain from the swap if anything?? just curious...
to make it simple so no one gets confused
stock ls1 heads coming off, stock ls6 heads going on. Im a full bolt on and will be putting my cam back in with the install. (FM10 114)

a .5 compression bump will give 2%, make it a full point and you get 4%
so 300rwhp x 4% = 12 rwhp + 10rwhp for extra flow, 22 rwhp should be obtained with thin Cometics.
