Thanks for the reply's the motor has been decked and I am running headers. As for the part number I am just going from what the guy I bought the motor from told me. He ran the 50 thousands head gaskets and told me all I would have to do was buy the correct 840 heads which I did, bolt them on and go. But since the motor is out I am going to go threw it jus to be safe! The motor has very little time on it from what he told me. Any way's thanks for all the info.
