We put the note in the catalog because the bore opening does not have the usual small block Chevy gasket shape (valve pockets). If the gasket doesn't fall into the combustion chamber in the head or the bore opening in the block the gasket will perform fine. The gasket has a pre-flatten steel wire-ring which will work fine with either aluminum or cast iron heads.
