Head gaskets for a 1998 Corvette LT1 motor

I will be rebuilding my motor (1998 Corvette 5.7 LT1) and I’ve read the main differences between the marine application and the car application are the head gaskets and brass freeze plugs. I will be using all the original bolt on parts.

I did not see the LT1 head gaskets listed on the web site so I emailed them, they emailed right back that they have no specific marine applications for the head gasket on a LT1 and I should use a high quality automotive application like an Edelbrock #7380.

Does this sound correct? Should I contact a Mastercraft dealer or would there part just be an automotive gasket? Could someone recommend a MC good dealer, I do not know of any local dealers.

You can follow my slow progress on my progress thread:

Thanks, Steve
