These are flat tops with a zero deck height. Heads were at 58cc but now unsure I will cc them when it goes back together. Total compression before was 12.78 to 1. But I am going with a slightly thicker head gasket to bring this down to 12.4ish level. I will know a lot more of this tomorrow. Cam is a custom solid roller cam from Crower. Crower makes power. Intake @ 0.050" is 270 degrees with the new 1.6 ratio 0.700" and Exhaust @ 0.050" is 278 degrees with the new ratio 0.702". Lobe separation is 106 and installed 2 degrees of advance.
