Default Re: Best way to clean vintage aluminum finned heads

put a set of much used, abused heads on a 40 coupe-the owner had me blast them and then he coated with a por 15 high temp paint and we cooked them in my powder coat oven for 20 minutes at 400 looked really good and they are now protected from dirt and fuel overflow
