commando's vs. eddie rpm's

I would like to find out what you guys think of the commando aluminum heads by MP as opposed to eddie rpm's. Different chamber sizes, different intake cfm, wonder if they might not be better for a small cube hot rod, asopposed to eddies with bigger ports, might have same velocity problems as j and x heads on 318- am I wrong? Similar price range. My car ain't a race car, might be quick but it's a driver. Would the commando's give me better street performance?
