Man, I hated to add a shiny new Holly part (fuel regulator) to my stock looking engine but it's there and it solved the rich condition during a stop plus the A/F moved up another 1/2 a point. I bumped up the timing and drove it for about 30 minutes and it's still pretty lean on the cruise circuit (12-13) and a little rich on the WOT (14-15).

I am going to let things cool down and get some sleep but tomorrow I will open the carb and lower the mains to a 1431 (.107")and change the metering rods to 1454 (.073" x .037"). Depending on how that goes, I may put the larger 1432 jets as secondaries to richen the circuit a little.
