well guys, i screwed up. [well that's not a surprise ! whistling]
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
