    The 43T spark plugs are a tapered seat but the other ones are a gasket seat. Which type do you have in your engine.
    The marine intake gaskets are usually different than the automotive. They have different restrictors for the manifold heater. Valve cover gaskets are the same but I'd recommend the neoprene ones.

      It has Champion RV9YC with a tapered seat in right now. Those were put in by the previous owner so I was hoping to validate they are correct. Thanks for your reply and great advice.

        I can't see someone mixing them up but to verify, if you look in at the holes you should be able to see the flat surface for the spark plug gasket. If that's what it should have.
