Milling head good idea?
I was thinking about milling the head to get a little more HP out of my ZC. Stock compession is 9.6:1....how high can I go and still use 92 octane gas? What kind of gains could I get?

i millied mine to the max of 1.4mm and decked the block for pretty good gains for the money. if you mill the head 1.4 mm you should net somewhere 10.6.1- i gained 25hp and 38 lbs tq the motor is not stock
