I'm not sure whether the plug heat range makes a big difference depending on whether you are running an iron or aluminum head, but it might. Snyder's recommends using Champion RC12YC in their aluminum Model A head. From a previous discussion of this subject on the MTFCA forum, question posed by Mark Chaffin, the consensus of several post respondents was Bosch 4203. Three other mentioned were: Bosch 4501, Autolite 216, and Autolite 66.

Lang’s list 14mm spark plugs along with the 14mm plug adapters. They are Autolite plugs. They list them on their web site and catalogue.
