You have the same setup as I have. I don't know about your block number but the head was used on 216s and possibly 235s. You must have the short side cover, correct? They made 216s and 235s in 1950 to 52 that had the short side cover but were still low pressure motors. I originally had a head with a Canadian casting number but it had a crack. I now have the same head as you and they are identical. The gasket set you need is for a 1950 to 52 Powerglide.
