Finally think I scored my first xj here. 93 4x4 4 door. Trading the guy an Xbox 360 some games and a flat screen I won at a Christmas party for it. A bunch of new parts but needs a head gasket job. I will have the head sent out. My question to you guys is is there any recommendations for upgrades on the head while I have it off the truck? May do a cam swap and header/exhaust while I'm at it I don't know. Fire away guys I wanna hear the experts opinions I'm too new to these bad boys to know.
