Repainting Headers...

Lighthorseman · Aug 8, 2013

I have pulled the old, tired 383 out of my Satellite, and am contemplating re-using the headers for my 440 that's going back in. If I am not mistaken, I can use the same headers. My question is this:

The headers are rusty, and I would like to clean them up and repaint them before putting them back in with the new engine. Is there any truly functional high-heat paint that will work - and not simply burn off?

I like the headers, but hate the way the paint just disappears, only to be quickly replaced with rust.

Thanks!

Use High Heat paint for a stove. This is what I use on customers manifolds:

Or you could send them out to be coated, not to sure of the cost.

Does it work ? I've yet to find anything that lasts.

I have used stove coat back in the mid 90's and it held up great. Not sure if that same formula still exists, but this time I got the POR15 black velvet paint and will try that. It has silicon dioxide in it and I know that is a component for extreme temp paints.

Recently had that done locally on a set of Doug's headers. Found out a lot of the same places that do powder coating, also do the ceramic coating as well. Hi-temp Black ceramic coating cost me $200 and some change.

We repainted our with, don't laugh, bbq paint...... Seems to be working pretty darn good out here in the Arizona heat.

When I try bbq black on my Harley I'll let you know. As far as experience goes,I've never seen any paint hold up for more than 30 seconds.

I beed blasted mine, and painted with some 2000 degree paint. it a bit higher in price but this stuff doesn't burn off like the cheaper stuff they sell at O'reilly's or autozone.

I ended up using 3 cans to get several heavy coats.
yes sending then out to be coated is better,

I tried some 1300-2000* VHT silica ceramic coating in flat silver "Very high temperature flame proof" header paint, in an aerosol spray paint & primer, that you bake on in an oven, I did several coats as they recommended, baking it on some 68 HP manifolds, {not worth the effort, headers are so damn much better} that I had ground all the casting flash & porous casting marks off of & then ported them, it actually lasted a few years, but the cam break-in period, was already done & then started the car a few times & let the heat cycle thru them & cool off completely a few times... It started to flake a little, after a couple years... my best attempt.... But I have yet to actually find paint available to the general public, that is actually worth a Chit...
