The heads are used, but I am going to clean them up. Will they end up flaking or peeling and end up looking like sh**?

mostly depends on the prep and type of paint. If you scff it a little with sandpaper it will stick.

They will chip eventually. Get them powdercoated.

I was gonna clean em' up as best I could, use rattle can engine paint, and I doubt I will be gettin' these powder coated. So, sounds like I'll be leaving them alone for the most part, for now at least.

when painting the exterior of your car... you would use an acid etching primer. (that adheres to the metal)
I don't much about engines but you needa high temp. paint & something to grab the aluminum. like an etching primer. maybe you can wash the aluminum with an aluminum prep-solvent? like dupont 244s. (metal prep)

Considering how much time it would take, it is a bad idea to paint aluminum heads.

another issue is heat retention. besides light weight aluminum heads have the advantage of running a lot cooler than iron. painting them could cause them to run hotter than otherwise would.

could paint seriously make it run hotter?
