unequal exhaust pressure
Got a question about an 80" shovelhead exhaust pressure at the end of the pipe. The front cylinder seems to have slightly more 20-30% more pressure at idle then the rear cylinder. (Not an actual measurement, just a hand behind the pipe.)
120psi both cylinders cold

Paughco 735D exhaust
Plugs look equal and toasty brown
The push rods are adjusted so that I can turn them with dry fingers. During the set up , I had to adjust them several times since I'd get a tap once the engine warmed up ( usually exhaust side) . Got that sorted, except for the uneven exhaust pressure. Any help?
