Im gonna keep the heads and get a more proper cam, my compression ratio is 9.85:1 and below are the specs of the cam I believe I need

Cam Style: Hydraulic flat tappet
Basic Operating RPM Range: 3,000-6,200
Intake Duration at 050 inch Lift: 234
Exhaust Duration at 050 inch Lift: 234
Duration at 050 inch Lift: 234 int./234 exh.
Advertised Intake Duration: 292
Advertised Exhaust Duration: 292
Advertised Duration: 292 int./292 exh.
Intake Valve Lift with Factory Rocker Arm Ratio: 0.488 in.
Exhaust Valve Lift with Factory Rocker Arm Ratio: 0.488 in.
Valve Lift with Factory Rocker Arm Ratio: 0.488 int./0.488 exh. lift
Lobe Separation (degrees): 114

With the 1.6 rockers and bigger heads I think this this should put me in the 4000-7000 area

Any disagreements?
