Hello Mark................ I second Cyboman's comment about using the coolant air bleeders on the back of both cylinder heads. And like Cyboman, I also have an air blead on the radiator but that bleeder also connects to a braided hose line that runs back and bleeds the air into the swirl tank. With the car running, all I ever do is jack up the rear end and go back and forth from head to head and bleed the air out of the system. I would take the car for a ride around the block and then bleed the heads again. Two sessions is usually all it needs. Let me know, I can send you a picture the head bleeders if needed.
