Don Ferguson Jr. #339 used to cast aluminum GMC side and rocker arm covers with Wayne insignia on them. He has the original Wayne 12 port head patterns but they fit the standard GMC heads as well. I purchased a set in 2,000 from him. He may still have some available. Don is at 310-379-4720 according to the 2015 membership roster. He also has the patterns for the Arias 12 port head and Arden heads for the Ford V8.The Ferguson family has been racing GMCs for generations and hold many land speed records.
Thanks, I'll give him a call....
