Valve Springs???
F13 - 230/232 duration .595/.585 lift on a 112 LSA
MS3 - 237/242 duration .603/.609 lift on a 113 LSA
HPE S cam - 238/242 .608/.612 lift on a 115 LSA
I know that the MS3 and HPE's S cam are bigger but i've heard good things from F13.. let me know
TSP Camshaft, PRC Spring Kit & Pushrod Package, it comes with Your Choice of Camshaft, Comp PRC Spring Kit with titanium retainers and valve seats, and Hardened Chromoly Pushrods, and get th ms3. the springs might be overkill as they are good too .660" but if you ever wanna go bigger than you wont have to change springs. It goes for $699.99. Ofcourse i dont know much about the f13 it might be better all around, I just say this kit cause its pretty much complete.
