I tried looking for an article like this already, or about stovebolt head compatibility in general but did not find much, maybe I'm just not that good at looking. Anyways, I was wondering if anyone would know if these heads have some differences that would not allow me to use the 53' 235 head on my 48' 216. My problem is I have a cracked head on my 216 that is cracked to the water jacket from outside above the intake and exhaust ports. I got a head from a guy I know who thought it might be the same, but when I looked at the head casting number "GM 3701887" it appears to be from a 53' 235, by my research. The head is not in great condition and will require a complete rebuild. I don't want to pull off my old head yet to compare water jacket and oiling holes as the leak is not major and I can still drive as is, and may consider patching it up for now. Thanks for any input.
