it's 11.6. zero deck, flat tops, 79cc heads, .019 head gaskets.
gotta change head gaskets. so guessing .040-.050 thick to lower it to around 10.5 or so ?
next would be, how much torque will be lost ?
sorry for the screwup on my end ! blush

1cc will change static compression about 1/10th of a point, some slight variables. you'll still be 11:1 with gasket change. add in some carbon build-up and your back the 11.5+. that's internet/magazine pump gas doable; but not in the real world.


so if you go to a .060 cometic summit sells. Its around 15cc compared to .019 4.5cc it would put you down 1 point to 10.5
