Exhaust manifolds can be resurfaced using a surface grinder with the typical universal cylinder head fixture. First start by tapping threads in the thru holes. I have 1/2”, 9/16”, 5/8” & 3/4” All-thread pieces cut to 8” or so, that I screw into the newly threaded holes. I add jam nuts to secure the rods to the manifold. — Then, using two more nuts per rod I pinch the all thread to the fixture, all the while leveling the manifold with a twist of the nuts. Its a cinch and gives a fairly solid anchor while enabling the ability to level end for end.
