needing to do a head gasket job on my 1995 454 magnum efi and would like to get it done this weekend because we are leaving for vacation the first of the week. a complete gasket set is gonna take a week to get here but I can get just the head gaskets in 24 hrs. my question is can I use automotive intake and and exhaust manifold gaskets, or are they different for marine, like the head gaskets? if I can use auto, how do I locate the right parts? look for applications that used a 454 in 1995? thanks!
