Well, to each his own! They are essentially the same block, just a slightly different bore, and the same minor difference in the head gasket. I'm guessing you used felcrap head gaskets in yours? Only way to go is a 20r head on a 22r block, with a toyota head gasket ofcourse!
Good luck on your build, there's nothing wrong with a 20r, I just prefer to go with the extra displacement.
