well i would not run it any more then .038 from deck . big pistons can rock if you have some piston to wall .you said you were going to a thin gasket . you can used a gasket with a smaller bore size like felpro f 1037 thats a 9.7cc some of the one size fits all have a bigger bore size 4.500.if a race flat top if will help at 060 bore but if not some piston builder mover the ch down to lower the ch and to deck the block so you need to check the ch and deck to that .you asking if quench vs CR ? well both is good by that you shure in the hell do not want a piston way down in the deck with hi CR but a flat top work better if the quench is tune in better then a hi cr engine ? no both engine work better both engine tuned in the same CR make s power it lets you run more cam for more power. if you can get hi cr with a flat top all the better i have a flat top i am building it will be 14.7 or so .all bbc engine have quench a open chamber still has some like said its nice to have it right
