who has ported aluminum heads for 360 Magnum block

I am building a 360 for a dart street strip car, it has a 360 /380HP magnum shortblock, M1 single plane, and a 600 lift Hydraulic Roller cam, who has a set of good ported heads for this type of combo?

Would take a used set if there are any out there for sale

Do they have to be aluminum?
