You should do what I did. Go to gude performance and buy there cam and head package... you get Ported and Polished Cylinder Head, High Compression Radius Cylinder, Racing Valve Grind, Ported Intake Manifold, Ported Throttle Body, Camshafts and the ECU... Its good for up to 50 hp and can give you a 1.5 sec drop in your 1/4 mile time.
It costs like $1695.00 but your whole top end will pretty much be finished. Gude is known for making cars run low 1/4 mile times (11's-14's) with all motor, no nos no turbo.
