I would just use the non-EGR manifold and get a spacer and put an Edelbrock on it. You will probably hear some on here say it won't work out but I added the spacer and put an Edelbrock on my '72 340 and it runs fine. Not a killer combo but the carb runs fine and reliably. If you don't want to do that just put on a spread bore Holley (won't need the spacer)
