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?
The camshaft is only good to 6200 rpm u need 7500 rpm to make power out of these heads also your compression is to small for this to work right.....u need something like 270 duration with 650 lift with at least 12.5 cr with higher gears and then this combo will work probably
