Query: Old Oil Return Design

This is a quality Felpro gasket but it does not include the latest design of the oil return hole. You can enlarge the hole at your own risk as rebuilders have been doing for years. Finally, Felpro incorporated the enlarged hole ( which looks like the profile of a Monopoly hotel on its side) into the gasket design, but the gasket set offered here is not the new design. Part number is the same.
