Well the quad's are bad about blowing head gaskets. We have a 90 beretta with the 2.3 quad (H.O).. it Blew a head gasket and it run like crap. But know it runs dang good after a complete overhaul and a few mods.... ha ha Are you getting any fire on the middle 2 plugs like any kind of spark. If you are then it is proably going to the the head gasket. Run a compression check to make sure..
