I'm really new to Y-Blocks. I have a 59 Ford Fairlane Convertible with a 292.The motor needs to be rebuilt. I have found a 312 marine engine, I want to take the heads off the 312 and put them on the 292.Also want to chane thei intakes want the 4 barrel off the 312. The 312 intake being a marine application dose not have the right hook up for a top radiator hose or tstat housing.Question is do they make an adapter to cross over on the heads or do I cut the front part of the water jacket on my old intake and machine it to fit. Really don't want to reinvent something that might already be in place. Thanks for the help Dave
