Robert will be able to help you for sure on the cooling. But, in short from what I've seen I imagine you need to establish a route from the back of the heads to bleed air that is trapped. This is easily done by drilling and tapping the intake manifold, I did mine myself with no trouble.

Put in two 3/8" fittings for hose and ran that to the water pump. This will allow you, when filling the system, to open the tube on the back of the heads while all the air escapes. Once full, re-attach it and you'll have an air free system.

Also, he can detail running a bleed from a header tank to the radiator top which helps immensely. This part will require some work if it wasn't engineered into the car from the beginning, but I think Blackjack took his apart to do it and has been fine with both mods. You don't need fancy electric pumps etc, all you need is a well-designed cooling system.
