Should I prep and paint exhaust manifold surface with prep and paint with 500 degree paint or go bare metal with the gasket?

Oh and what about forma gasket? should that be used with the exhaust gaskets?

I would paint, but high degree paint not necessary. Paint on the bottom where it bolts to head will burn off no matter what you use - the rest does not get that hot. I always use a sealant with the gaskets to fill in all the nooks and crannies - others may not. Just re-read your email. If your talking about painting the mating surface, I would not. Just bare metal.
