As long as you have a pre 85 22r block to work with, the head should bolt right up but you have to have a 20r intake too. if the block is 85+ it can still be done but its alot more costly because you'd have to have the deck machined down to the correct height for the timing chain to fit properly and ya da ya da ya da. There are alot of options out there to work with. if i were you and had the right block, id definetly do the hybrid and build the 20r head with maybe some over sized valves, cam, springs, retainers, big carb, exhaust, etc. You combine the higher compression with a solid bottom end and built head, id be willin to put it on the line with a 5VE anyday. Of course this is in a perfect world where money and time isnt a concern lol. Another thing to look out for if you do the hybrid is rocker arms, the 20r rocker arms are steel and the 22r arms are aluminum which are lighter and quieter. Atleast im 99% sure on that but dont kill me if im wrong. Im assuming any transmission that went with a 22r would work and im sure you would have to change your drive train with a few of them, im just not sure which ones. Hope im helping!
