How to Grind your Exhaust Manifold Donut Seating Surfaces

This video is on using a Black & Decker valve grinder to rework the donut seating surfaces on old Chevrolet rams horn exhaust manifolds. The stone size that I used was a 2.5" diameter with a 45 degree bevel. This worked really well and left me with a great surface to work with; I no longer have any exhaust leaks. Below are the addresses my YouTube channel which I no longer have access to, my Instagram page, HRI Services welding Facebook page, and the Classic Chevy Parts page.
