Rotor wannabe ?
Over-rich mixture will cause lumpy idle.
Lots of overlap on the cams will cause lumpy idle. Poor vacuum signal for the MAP sensor will cause lumpy idle. Have you fed the four vacuum tappings into some sort of "accumulator" can to smooth the signal for the MAP sensor ? Can you get hold of a wideband O2 sensor and gauge so you can actually see what lambda you are running at idle and at 5500 rpm ?
