Must be thinking of someone else. No worries

This is a for a 4.04" bore small block I'm building. 4.125 gasket bore diameter will be plenty. A 4.080 gasket will clear the chambers but there's a slight chamfer left at the top of the bore and maybe a little core shift that puts it to close for my liking.

Hi, I'm looking for a new pair of Cometic c5457-030 head gaskets. Bore diameter of 4.125 and .030 thick. Thanks guys
