This is a 1947 Allis Chalmers antique tractor cylinder head that came in for a valve job & surface. Both the intake and exhaust valve seats were heavily pitted and eroded so we machined all eight seats for hardened seat inserts. We then machined the new hardened seats with our three angle seat cutters for the valve job and then milled the surface smooth and flat.
