Rob, Your story sounds just like mine. 89 4ze1 with new AMC head. My head gasket lasted about 14 months and blew. Same scenario as yours. I called the AMC outfit on the Left coast and they said first don't use the blue Felpro head gasket because it doesn't "stick" like the silver graphite or whatever. So I used the silver from some off-brand. That's the one that lasted the 14 months. I called back and they said they have been hearing a lot of head gaskets going bad recently and recommended that I use an official Isuzu head gasket ($70 <img src="/forums/images/graemlins/scared.gif" alt="" /> ) which I then installed. So far so good. I also may be in the market for a radiator; do you know if the V6 will fit in the 4 cyl car without mods?
