I re-itterate, it can be done but is a pita. Do a search for my thread on it and in one of the last posts you'll find a link to a page explaining how to do it. First things first though, you would do what marlin said you need to to run the 20r head on an efi block, then do what the page says to use the efi intake plenum. It is a big pain in the ass but can be done. I still want to do it but currently don't have the parts/resources.
