olds 455 cylinder head model numbers

Hi, does anyone know what model or series of cylinders heads are needed for a 1973 Oldsmobile 455 marine engine. I'm pretty sure the bolt pattern on the exhaust side are not the same as standard automotive heads Thanks Jim

Thank You Bondo, I just assumed the exhaust ports would be different. I have worked on cars for years but this is my first boat. My son and I are restoring a 73 Glastron Carlson cv-19ss So far it's been a lot of fun and a learning experience. Thanks again
