Can someone tell me if there is a cc or valve size difference in the small letter ECZ-G and the large letter ECZ-G Y-block heads? Thanks, Jim Griffith

They are the same.The replacement "113" heads had a larger 72cc chamber vs. the 69cc of the "G" heads. You can find all the info for these at ford-y-block.com

Thanks Chalupa55. I have one small letter and one large letter and was concerned about mixing them. Jim Griffith
