will a 22R head (EFI) bolt on a 20R block??? and work a direct fit..and do i need to use the 22r dizzy ????

 

why would you want to put a 22r head on a 20r block, isnt that kinda like working in reverse. You'd get less power, lower mpg's, and I wanna say there is a lot more to swapping a 22r head on a 20 r block, than just swapping a 20r head onto a 22r block.
