ok. i blew my old head gaskets. i bought the frpp replacement a302 head gaskets, and the gasket is trim to fit on the water jackets. what do i use to trim the gasket with that wont warp or damage the gasket, i was thinking either a punch or a dremel tool
You don't need to trim or do anything with them. I have replaced them a few times for doing things wrong. Just drop in place and use a little sealer to help them stay and your down.
