Do you use Primer on your engine before you paint it?

I just use plain ol' Rustoleum bright red for the block (it appears to be the same shade as '67 273 red) with Rustoleum brown primer first. I don't think the block gets hot enough to need header paint on it.

As far as headers go, I've tried all the "high heat" rattle can stuff, and it never lasts. I mentioned it (that header paint sucks) to a guy who does powdercoating and stuff and he said that if you look closely at the directions, they state that you need to bake it (or start the engine) about 20 minutes after applying the header paint.

Ha!.....good luck, I could never install the headers that fast and I don't have an oven that big at my house. Anyway.....that's what the directions said on the header paint I was using. I ended up just nickel plating my headers for $50.
