I have two Merc 165 heads and both are cracked. One on the side of the combustion chamber and one through the valve seat. Can I put an automotive style 250 or 292 head with out the integrated manifold, or is the combustion chamber different?
Just had these parts in hand. The marine manifold is a combined intake and exhaust manifold. All one casting. The automotive head with the integrated manifold won't accept the separate marine manifold.
