We are pretty sure you did mean 235 Tam Trucker so I won't let anyone beat you up for a simple typo. The heads are a little different but they will interchange. The are some additional holes in the 261 head often referred to as "steam' holes but I don't know where that came from as there is no steam involved. However it is necessary to make sure the head gasket used also has these little gems or there will circulatory trouble ahead. Kind of like a blocked artery I suppose. I have not done this procedure but am told that the holes can be drilled in the 235 gasket. I think (w/o looking) there may be some additional info available in the archives so I'd suggest a thorough search as I always do. There has been a lot of discussion about using 261 heads. But WTH, "if" your needing a new engine why not try for a complete 261?
