street heat vs. GT-40?

[69fastback]

I have a trick flow street heat intake and a GT-40 intake and not sure which one to use? Or I was also thinking about selling both of them and going to the track heat, or perfrome rpm 2?

The car is mildly modified. Has all your basic bolt ons. Headers,
pullies, 3:73s, 65 mm tb, CAI, windsor JR. heads, a wolverine cam (need to find specs on it. it is more of a street strip type cam). All forged internals for a 150 wet nitrous kit. 24lb injectors, 77mm mass air. Typical exhuast upgrages o/r x pipe flowmaster cat back. Another thing is it is a t-5 if that matters or not. Any thoughts on this are appreciated. Anything else i left out that will help please let me know.
