    hi folks I wonder if anyone can help ,I run a very nice 635 csi 1981 vintage,and I was going to remove the head ,to carry out an overhaul. until in a recent chat with a fellow owner, I was asked, why not replace it with a head from a later model 535 i sport ? apparently this is a more efficient item and it fits.If this is so I will have to get one.I am told they can be identified by numbers on the head (cast or stamped ? ) anyone know? or have one of these for sale.any help appreciated
