Engine Paint
I have a 1972 cutlass 442 with a 455! I just painted my engine with POR15 and already I'm getting change of color by my intake and by my exhaust manifolds. What paint brand do you all recommend. I contacted POR15 and they told me this is common for Oldsmobiles and Pontiac engines.
Check out the pictures.

That always happens. It happened when they were new.
It even happens no matter how many identical threads you start about it.

I like Bill Hirsch paint. I use Bill Hirsch paint.
I've driven by the warehouse and bought Bill Hirsch paint from Bill Hirsch himself.
If you really want, I'll post photos of the same spots painted with Bill Hirsch paint, burned the same way.

I painted my manifold with por20 aluminum coating. Mine did not discolor at all. I also painted my headers. The headers did blister in a few places, I believe because there was oil on the tubes. It did not discolor on the headers either.

Crossover is not blocked. I was going to block them but heard a lot of stories of the plugs getting loose and rattling around. The por20 is a special header and manifold coating that has aluminum in the paint and only available in aluminum color. I just looked on their website and it says por20 has been replaced with their high temp paint. Apparently it does like the heat as much as the por20.

If the crossover is not blocked, and the clearcoat has not discolored, then that's a very impressive clearcoat.
You'd be hard pressed to find a colored engine paint that will do that, though.

It's not a clear coat it is aluminum color, which made the old stained manifold like new again. I agree though no regular colored paint would last. On my small block I painted the manifold gold. After a few short drives it burned near the crossover.

I see people do this is all forums. I just don't understand why folks think they'll get an answer faster or better by carpet-bombing the site with the same question. It's actually in your best interest to keep all responses in a single thread, since that allows folks to spot and correct bad information that may have been posted. Good luck.

I had a shop powder coat a set of valve covers for my 64 98. They turned out great. Of course, valve covers don't run hot like exhaust manifolds, but you can get different kinds of coating.
My headers are the coated ones and they aren't discolored at all.

#22
I've been told to use wood stove paint on headers, has anyone tried that?
#23
I used BBQ grill paint on exhaust manifolds before. It worked ok. The paint did eventually burn off, just like the VHT Superhot I tried. I think the only way to get a good coating on manifolds or headers is powder / ceramic coating or chrome.
#24
I'll just add to all this that if you start off with a shiny or glossy coating on anything that gets hot it will eventually turn dull or satin like. It may not burn or discolor and get brown but they dull every time. It's the nature of the beast.
#25
I put out good money for stainless headers and they discolored almost immediately. The motor has about an hour of run time on it. I'll live with it but I wish I would have bought ceramic coated headers.
