My "EAB" heads had the casting #'s ground off. I only know that's what they were because I took time to cc them. Plus the rebuilt engine they came from had an EAB crank.

Has anyone ever seen an intake that was marked anything BUT 8BA/8RT 6520? From what I've seen that casting number was used from 48 thru 53 on Ford cars and trucks.

The only variation Ford used was the merc intake for the teapot carb with 4 bolts.
