Hello. I am looking for input regarding the direction I take on my engine rebuild. I have a 1962 235 that runs, but needs overhaul. I have access to a 261 block and crank from 1962 261. It seems that parts are hard to come by for the 261, especially the head. I cannot source a head anywhere. I have been told that a 235 head will work, but three steam holes need drilled. I have access to a 235 head, for a price; the 261 block and crank are free.
Any suggestions? Should I try to go with the 261? Or, should I stay with the 235?
