You're right. I misread. But either way, neither are tinted.
Ford wouldn't presume the liability of tinting either heads, or tails from the factory.
Hell, all one has to do, is to go out to any dealer lot for themselves and look.
Back on topic, local company I used to do my heads and tails, used a vinyl film. It wasn't Lamin-X, but IDK what mfg'er it was either.
I mentioned this in PM to dje624, when he posted about his (albeit negative) experience when removing the film from his heads, which he said damaged the exterior surface.
I noticed a bubble in/on one of my assemblies, which I took back to them, and they removed the original vinyl material, w/o any adverse side effects.
Hope that's of some help to the OP.
I've heard of people having used the VHT "nightshades" spray on stuff, but the results weren't nearly as good as with the film.
