Can you Ceramic coat them?

Does Powder coating hold up to the temp?

Any other suggestions?

Thank you

The key to make the paint last a little longer, is the clean & prep them properly. THEN, when you paint them, paint the exhaust ports with a VERY light dusting ONLY. First coat to where you can hardly see any paint on them at all. paint more on the rest of the heads... come back to the exhaust ports and do another VERY light dusting only. Let it tack up and repeat this about 5-6 times until you have JUST enough paint on them to cover the bare metal and stop!

I've had mine painted for almost 9 years now and while the center ports have changed color, it's not flaking or totally burnt off yet. I'll be pulling the motor this winter to fix a rear main seal leak and will repaint & detail the engine bay again...


Hope that helps - Brett!

dont drive it! that really helps....lol..

I painted mine like Brett says, BUT after 25,000 hard miles, not much left of the paint, at least none on the exh ports......lol

Buy aluminum heads. No painting required.

LOL, Yeah i thought about aluminum heads, but was hoping for a more wallet friendly solution!

Not sure how it would work, but you could try high temp paint for exhaust manifolds as a base coat and then the top coat.

Just an idea...

I like the patina of a slightly crisped exhaust port

I know somebody who tried that. The base manifold paint stays OK (I used it on the turbo on my '80 Turbo Bird) but the engine paint still burns.

Interesting....just how hot does the exhaust port get? I have an infrared laser thermometer, but my engine wont run right now!!!

Anyone have an idea what heat range these things produce?

I also want to know if anyone powder coated their engine and how it has done over the years. I'm thinking I might powder coat the sub frame, floor pans, wheel wells, trunk pan.......... I want it to last FOREVER.
