Doesn't really sound like it's lean because you don't have the problem accelerating, sounds more like cruising RPMs. I'd check the manifold vacuum on it & see what you have. That can tell you a whole lot. I'd also check the float levels & make sure they aren't too high or being pushed off their seats from too much fuel pressure. Make sure the correct power valve is in it & that it's not blown out.
As for the ignition, any plug that can fire from points should be able to fire in an electronic ignition system. The only real difference in EI vs point is how the coil is triggered. Timing of course needs to be correct.
Is this a solid lifter cam or hydraulic? Valve clearances need to be correct on a solid & lifter preload on a hydraulic.
