I picked up my truck about three years ago and about a year after I got it it blew a head gasket. I am just now getting around to fixing it and havin some probs it seems to have been modified some it has a webber carb and no erg on it I want to rebuild the carb while the head is at the machine shop but don't know the model. I was also wondering about if I was going to have problems with the new gaskets due to the mods on the intake. Any help would be very appreciated.
