Does anyone know how to get around the problem of flaking paint and rust on the 389 block near the exhaust manifolds and on the intake near the carbie? Any information would be appreciated,Thanks.

I've used red oxside primer before I painted the heads but they have to be comlpetly clean, but the center exhaust ports will always burn off the paint to some degree. It gets extra hot there because of the 2 ports together. Almost no way to stop it except not to start the engine. I'd go talk to a powder coater to see it they have anything that will not burn off, but I don't know of any sure way to stop some burn off.

Im working on something, will let you know if it works.

Not sure about the exhaust ports, but I had success with the intake. I used stainless steel shim stock and blocked the heat cross overs. I have a 66 tri power and my choke still works fine and the paint is not burning!

I paint the exhaust ports on the heads with high temp exhaust paint and the rest of the heads with normal engine paint, same with the exhaust crossover on the intake,

I used the KBS high temp paint followed by the Bill Hirsch paint.

It does work pretty well. The blue will burn off and leave a gray/silver instead of rust.
