Non-cvcc(canadian) head that fits 83 EM1 USDM?

I have a 83 wagon with the EM1 motor that i bought in may with blown head gasket. Pulled head and found that it is cracked from the aux port to the intake and the lobe on #4 exhaust is flat which ruined the rocker. My machine shops wont touch it and the ones that will want way to much. So i ordered another head and found it to be warped on the cam side which also had the same cam lobe bad. So i looked online and found a non cvcc head in canada, called the yard gave them application and they have one that will fit they say but he cant give the casting number due to its not there and they are the middle man for alot of other yards. Finally my question does any one think it will fit or worth the risk of ordering, and does anyone know which non cvcc heads fit the EM1. If posted in wrong area terribly sorry.
