Will 235 and 261 heads interchange with one another?

Later 235 and 261, yes. But, which way are you going?

A lot more details such as year & casting numbers are needed for anyone to answer.

Using a casting number 848 head on a 261 will result in somewhat higher compression, but some extra coolant passages need to be drilled in the head to match holes in the 261 block. A 261 head would be a drop-on fit on a 235, but the compression would be lower than with a stock head.

That helps a lot. I asked the question for a friend of mine and I'm not sure what year engine he has.
