If your swapping the cam, then porting the heads will complement the cam very well. It greatly increases the efficiency of the engine across the entire usable rpm range and lowers iat2 temps.H/C are next on the list (after putting a tire on it). The tuner (big LS/Vette shop) said my next move should be cam, valve springs and ported SC/Snout. I asked about porting the stock heads and he said it isn't necessary at that level which seems contrary to most.
