Boy, I don't know about running the GT-40P's on a 347 with F303. Even ported, you're looking at intake flows of 230cfm max and exhaust of maybe 170cfm max, and those are with perfect port jobs. With the added displacement of the 347, you just may not be able to get the amount of flow that the engine wants. Have you considered something like the AFR or Dart Jr heads? The P's are great with a 302/306 combination, but I'd be looking at a different head for a 347.
