What size combustion chambers do stock E7s have?

I'm trying to figure out if I'm going to have higher compression when I install my AFRs or will it be the same? So, I'm figuring if stock heads have bigger combustion chambers than 61cc then I should expect more compression when I install my AFRs.

BTW, does anybody have any idea what my compression will be when I install my AFRs w/ 61cc chambers? Oh yeah, my shortblock is stock. I'm just gonna be putting in new bearings and rings.

I think the stock E7's have 64cc chambers. I wouldn't expect much of a bump in CR, probably still in the low 9's.

I you're putting in new bearings and rings you might as well get some pistons with valve reliefs big enough for those 185's. Then you can run a big enough cam to keep up with them.

i don't have enough money for pistons. Rings only cost like $20 or $30 and bearings cost about the same. Pistons cost in the neighborhood of $300-$400 for some forged ones. I don't have that kinda of extra money.
