Just wondering if I can fit an RB25 head on a 20 block. I'm in desperate need of a new head and nobody seems to have one. My car is my daily and I need some options. Worst case I can buy a whole RB20 and scrap the block, but that seems like a waste considering I was going to swap in an RB26 next winter. Any input would be appreciated. Thanks!

Nope, I believe the water jacket/oil ports don't line up. Wanted to do this on my old 20 as well. 20 or bust!
