5.9 Magnum exhaust/intake combo help

Rob, the stock head port its bolting onto probably ductates its useabke powerband. Look at a std strip dominator then a w2 strip dominator with its larger ports, i get it says 7k too. Fwiw i ran a w2 Strip dominator on LA X head 340 and it ran fine with a 284/484 MP cam, mismatched ports and all. I got the intake in a straight trade for a performer...still think I came out ahead.
