How long between failures? Was everything checked before you installed another set. At the bare minimum you should check the heads and block deck with a precision straight edge and feeler gauges before installing. I always roughen the surfaces up with some 60-80 grit too so shiny spots or previous head gasket blowout spots are addressed. As for gaskets the stockers work well and the Fel-Pro 9441's are about the same exact thing. If you want a little more bite the Fel-Pro 1007's will work well but you have to have the receiver groove put in the head and you may damage something else since the gasket will hold up. Same goes for a single steel shim, it may hold but your pistons or rings may go South! Figure out why you are blowing them first or you will be a pro at putting head gaskets in before you know it!
