I can let you have a good CB head for your 91 164 compressor but reusing your old head gaskets may or may not work. You will have to be very careful removing head bolts and lifting off old CB head, gaskets and reed valve plate. You should use a torque wrench and an alternating cross-sequence to torque head back to compressor. Bolts are 8mm with 13mm hex head so I would torque to about 15 ft lb since compressor and head are Aluminum.
Pay attention to alignment pins on how reed valve plate fits head, body and gaskets.
You will need to add correct amount of oil and of correct type. If a R134a conversion use Ester oil.
