Ive done alittle searching and didnt really find much on how much you can take the combustion chamber out to? I want to know what people are opening up the combustion chamber to on the ls3 style heads? I have a buddy trying to lower his compression alittle bit more without using thicker head gaskets. Ive read that stock on the lsa/ls3 heads are 68.4cc.

Richard at WCCH opened my LSA heads to 73cc not sure how much further you want to go but I would be cautious with an LS3 head in this area.
