I have full bolt ons with the ls6 manifold and a tsp 225-225-112 lsa.. I just purchased dart 225's with 2.08 intake and 1.6 for the valves... i was wondering if the valves or the 225 was goign to be too big for my set up and if i should of gotten 205's. and what kind of gains should i get with the heads i bought.. Thanks
