Same bolt as me.

Dont drill it.

The manifold is cooled by coolant, it needs a gasket that seals all the holes up. I have one and will take a pic tomorrow for you.

the elbow has a hose running to it from the heat exchanger. The elbow is raw water cooled.

got the correct elbow today from American Diesel ( all those who have never measured something wrong, raise your hand. Thought so.) my question now is do I need to paint it with a high heat engine paint?

You don't have to paint it. But I painted them, and other parts, with Ford red that you can get a most auto parts stores.

Assuming your engine is red.

Thanks, Capt Bill, If I do paint, should I mask off where hose clamps & mounting surface?

I painted the entire elbow, excluding the flange facing onto to the manifold, with engine enamel, without undercoat. Before painting I cleaned them with degreaser to ensure a clean surface. The paint job passes the test of time, save for some heat discoloration.

Thanks, I'm thinking a good acetone scrub, then a couple of coats of paint with it sitting mounting face down on my bench

Sounds good, the elbow could have an oil coat to prevent rust on the unpainted surface.
Oil coolers I bought (from US) came in grey undercoat,just had to spray them red.
