6404D engines

I have these engines, installed in 1974. The cast iron intake/exhaust manifold and reverse rotation camshaft (starboard engine only) might be the hardest items to find. I removed my intake/exhaust this fall to replace the gaskets and inspected the cast iron. It's very thick. I suspect a shop experienced in cast iron repairs and resurfacing a camshaft could deal with these rare parts.
