Drill it, tap it, and run a short bolt into it. First make sure there are no cracks running out from the hole, though.

I arc welded mine with 7018 rods.

Remove the manifold,do not attempt to weld or repair it on the engine.A few years back I saw an H in a shop,torn down..the result of someone welding on the manifold while it was still on the tractor,few pieces of slag ended up in the cylinders and messed the tops of the pistons.
I had one repaired and it was OK,it was a dual fuel manifold. I put a new manifold on another H.The new manifold is smooth inside,no obstruction or rough surface and you get better flow,the tractor with the new manifold outshines the tractor with the repaired one.

You can also braze it.

Is it on the exhaust manifold at the middle where the 2 halves come together? Had a problem like that on an M. I think I mig welded it. It was not too critical being on the exhaust side.

You could try some of that epoxy putty stuff. Sure would be easy to apply.

I brazed mine 20 years ago on my Super A. Still works fine.
