The rougher the idle, the worst that condition will be.

Sealed Power CS-113R, solid flat tappet cam will fill that request. It would have a bad (meaning good) idle and produce good low end torque and high end horsepower. Cam range is from 2000 to 5500 RPM.

Sealed power CS-113R solid lifter camshaft specifications:
228 degrees I / 230 degree E valve duration
110 deg. LSA
.395" I / .401" E valve lift with 1.5:1 rocker arms
.421" I / .428" E valve lift with 1.6:1 rocker arms (350 CI engine)
Use with 9.5:1 to 10.0:1 static compression ratio.
Comp Cams 813-16 solid lifters
Ouch! that is a tiny cam. it'll run on garbage springs and last forever but don't expect spectacular power.

The 401A3 will be a better match for your goals, provided you run good springs. I'd advise supplementing the cam oiling somehow too, either grooving or face oiling lifters.
