I have a stock LS2 with bolt-on's & a 2 stage shot of nitrous (150 hp total). I have a set of built L92 heads all Manley valves, springs, titanium retainers, bowl work & milled .025 along with L92 truck intake complete with 39 lb injectors. Since the heads & intake are just setting around for my future built motor (next spring) would they bolt onto my stock block LS2 motor with stock cam & not have to worry about valve to piston clearance? I have a TrailBlazer SS 06 & I am running 12.12 @ 112.93 on nitrous as is full weight. I am pulling 300 lbs weight for my next run also added a behind TB 2 stage plate since the last run. On test that GM high Tech ran these heads added 44 HP. If I knew my valve to piston clearance was ok I would just use them till I get a built short block next spring. At least with the heads & the 300 lbs less weight plus new nitrous plate I could play in the 11's till then. Any feedback on the Valve to piston info would help me decide. I don't want to tear it down to find out it won't work. Thanks.
