Here's a few shots of the exhaust crossover hot water plumbing. There is a 1/4" restrictor bushing in the elbow on the drivers side head and one in the tee on the passenger side head. Hot coolant will flow from both heads into the heater core, with the heated coolant flowing from the drivers side head through the exhaust crossover passage.
The brass pipe fitting assemblies will become more compact as they have not been tightened completely. The engine is not assembled yet, still in the mock-up stage checking for accessory fitment. An HEI distributor fits next to the plumbing with no clearance issues.
