a situation came up with my head. It has been resurfaced .010 when i recived it. Now i found a little "scar" close to the cumbustion area, the way to fix this problem is to have it resurfaced again .010. Now this will put the head at -.020 from stock. My question is, will .020 be to much on the B16a motor with the factory head gasket while running your Spec B cams? Will i have valve to piston clearance issues? Thanx
