I had a cracked head on my 1981 cruiser and I ordered a gasket set from SOR. Only thing is the head gasket did'nt fit properly. They changed some of the holes slightly on the front of the block. This seemed to be a 1980 to 1981 difference though. Just make sure the your heads match up. I found that over the years there where a few differences like that. Or upgrades as they call it.
