L92/L76 or FAST 90/PRC 5.3? I figured I'd ask the fellow Texans here what I asked in the tech forum 
I just got a forged tsp 408 with -12cc pistons. Currently, I have some TSP PRC 5.3 2.5r heads flowing 308cfm, milled 62cc with a ported FAST 90. The cam is a Texas Giant cam.
My question is, this: If I switch over to a L76/L92 setup, would I be gaining a significant amount of power? It seems as though I may be able to recoup all my costs if I go this route, but would love to hear what you all have to say.
