241 heads compression question
Factory LS1 is 10.19...LS6 is 10.45
241 chamber volume is 66.67 cc
243 chamber volume is 64.45 cc
I believe 6.7 thousandths of mill equals 1 cc of volume reduction
I wacked my 241s .030 and figured to be @ 62.2 cc for 10.75 with GM mls

Depending on the cam size (less than 230 IN.) some will run the .040"
Cometic gasket which puts the quench @ an ultra tight .032" and will raise
the compression another .35 to one. But some end up flycutting for PTV
clearance which negates the squeeze increase.
