1935 Ford flathead V8 aluminum heads
 

I have to repair as small crack in one of my aluminum heads on the 35 ford coupe. Can someone tell me if those heads were originally factory painted along with the rest of the engine?

No paint from the factory.Commercial applications which were cast iron were painted.

Thanks, makes the weld repair a lot more challenging. :(

Depending on where the crack is there could be additional issues. If there is a lot of corrosion inside/behind where you are attempting to weld it will not react well to the heat of the weld. It is possible to end up with a bigger problem.

I bought some special high strength aluminum epoxy on Amazon and used it to repair some broken bolt bosses on a Navarro Universal intake manifold. Two years down the line, it's still holding. I don't know if it would work on heads; just suggesting a possible alternative to welding, which, as "JSeery" said, can make a big problem out of a little problem quite quickly on old aluminum castings.

It is a small hairline crack seeping coolant along the line illustrated by the blue mark on this picture. Turns out it is positioned directly over a coolant port on the block. I toyed with the idea of using one of those new nanotechnology fiberlock head, gasket & block repair products I have heard has had some success. Thinking welding would be a more reliable fix.

IMO I would reconsider the welding option, it would be a shame to destroy that nice of a head. But that is just me.
