.0042 = 1CC This is straight out of the old Chrysler engine book. Also for every .010 milled from the chamber side...mill .0123 off the intake surface...so if you mill .050 off the chamber side you would mill 5x.0123 = .0615 off the manifold side.



Do they spec a different milling amount per CC for the closed chambered heads? I would think they would require more milling per cc because of the chamber size.
