Not to be a Dick, but poorly ported heads can actually reduce performance significantly. Does the guy that ported the heads have a clue what he's doing, and access to a flow bench, or did he just grind metal away until they were "ported and polished". Big block fords have some of the biggest Ports available in factory heads and someone porting heads can easily and quickly ruin them.

Point being, ask if the dude flow bench tested them for actual air flow gain (with real data to back it up), or if he just "ported" them. If he just "ported" them, I would swap to your original heads and see what happens with the other upgraded parts.
