Some of the hot-rod techniques are about getting more air and fuel into an engine. Some are about running higher rpm's. And some are about running the engine more efficiently. I've got an unbuilt 350 SBC in my shop, and I planned to use some of their efficiency techniques.
I bought hypereutectic pistons, which transfer less heat, keeping it in the cylinder where we want it. They are stock on Corvette's. I also bought a coating kit for the engine. Slick stuff for the piston skirts and cylinder walls, and ceramic coating for the pistons and head. The ceramic also has aluminum in it. After you bake the ceramic coating on in the oven, you buff the top to remove some of the ceramic and leave an aluminum veneer. So you end up with a reflective surface with ceramic insulation underneath. The kit wasn't very expensive.
I don't think I would tear my engine apart just to apply the coatings. But if I had to rebuild my engine anyway...
