11.25:1 , I am having the heads milled down around .020 to bring the Heads from 64cc after BJR's work to around 59cc. Might have to mill the intake side of the M1 also. I will see here real soon. Cylinder pressure should be around 195 - 205...
The reason I want an MLS gasket is for the future use of a 200 shot of NOS.
Not that I will hit it right away, just want to be prepared. And not cringe when I hit the button. Or have the great possibility of replacing head gaskets. I am more than likely being overly cautious!!!!!!!!
