If the intake is moved to the other side will there be distributor clearance issues? And if you raise the intake to clear the dizzy will there be hood clearance issues? I don't know, just a thought.
If your going to modernize the head might as well fix a bunch of other items - doesn't cost any more while the patterns are being made..

Put injector bosses directly in the head so the injectors spray hits the back of the intake valve. For non-efi use put a plug in the hole.
