Is anyone running the RPM 'air gap' manifold?? How is it?? Or would performance be similar with a torker manifold??

how are the spec's edelbrock gives for combinations of parts when using their products??

For example; I was looking at installing the 'air gap' manifold. they recommend a 650 or 750 carb and the cam they recommend is prt# 7122,

(Duration at .006 Lift: Intake 290° Exhaust 300° Centerlines
Duration at .050 Lift: Intake 224° Exhaust 234° Lobe Separation: 112°
Lift at cam: Intake .310 Exhaust .325 Intake Centerline: 107°
Lift at valve: Intake .496 Exhaust .520
Timing at .050 lift: Open Close
Intake 5° BTDC 39° ABDC
Exhaust 54° BBDC 0° ATDC)

NOTE: Adjustable pushrods or rocker arms and screw-in studs required.)

Adjustable pushrods or rocker arms sound like a tuning night mare for a rookie???

thx again
