dude just bolt all your 20R parts on that 22R block, if its the early 22 its just a quick bolt on deal
22short block+20R timing kit+20Rhead and intake+header or 22exhaust manifold
oh yea use the timing cover from the 20R also, on top of that 20R head use 22R rockers and i used the 22R valve cover cause the rockers were hitting the 20R valve cover with my LC engineering .460 lift cam
