What would you say is a good paint for valve covers , painting over old paint .

I'd clean and prep the valve covers with acetone or another paint stripper and then pick out a high temp spray paint from the parts store.

do-it best hardware sells a paint stripper with a little spray bottle attatched to the can so you can just spray it on and wash it off with water and man does this stuff remove paint.....I use it to remove the paint on all my carb and mag rebuilds and then repaint with the high temp ceramic coat engine paint from advanced auto parts...all this seems to work real well on mags and carbs...don't see why valve covers would be any different....if they are aluminum give'em a shot of zinc chromate first

Sand blast it it will be a lot better job I use acrylic enamel and bake it at 250 for a hour and it will last alot longer

I speculate that you mean automotive, acrylic enamel. Likely a 2-part acrylic urethane. I mention this because at every architectural paint store and home improvement store there will be some paint that says "100 acrylic" and "enamel" on the can. This is NOT the same thing.

I was putting my motor together and while I had it apart, I sandblasted the valve covers and then just cleaned them off good with some acetone before paint. As far as paint, I went up to my local airport to the part store and got some $7 cans of aircraft engine enamel. Kept it cheep and if I ever need to coat over it's real easy.

For $60 goto Harbor Freight buy the powder coat gun and find and old oven, works great! No Runs no Peeling! I order my powder from powderbythepound.com. If you get the "Vein" two tone powder it will hide any imperfections in the cover and only takes like 20 minutes to complete.
I powder coat anything I can fit in an old household over including my dry sump, flywheel, alt case
