Thanks for all the input guys. I guess for now, I'll just tune what I've got and go from there if better heads isn't going to pick up anymore on a stock stroke 340 than a set of stock X heads with a good valve job.
What do you guys think would run better? Torker manifold, or RPM Air Gap? Eddy 1406 600, or Holley 750dp? It'll be interesting to test all 4 combos. I've also got a 1" spacer to play with.
