Also, 0.30 is ok as far as intake fit. Over that, you need to figure the angles, and remove from the manifold base to correct the intake port angles, and maintain the sealing clearances.
Thats what i was thinking, gotta call the machine shop to see how much they charge to mill....depending on price might be cheaper to buy different pistons.
