Paint burns off heads

Thanks
Will give Duplicolor a try.

Also having the right timing when engine is first started, if its too far retarded it will burn it right off. Plus I get the moisture out of the heads and block before spraying. Usually with just a burnsomatic torch.

Yup
When I first got the wagon the po said it ran hot. Checked the timing and it ran quite a bit cooler and I had the first piece of the puzzle to make it run nice.
Timing matters.

Even Duplicolor burns off FE exhaust ports, regardless of preparation. I went through it twice. It goes flat initially and then begins to flake over time. If you're running blue there are three different Ford Blues.  The variances are by year.
