What main jet's /idle jets are you running.  My car came with 145 mains (middlin emulsion tube)  and F8 55's.  It was a tad lean on the low end so went to F9/55's and that dealt with the lean muffler popping.  I may try 140's as I suspect an over rich on top.

What do you run.  All individual throats are balanced as are the two carbs.

The only mod is an SBD uprated cam (mild still use the original tappets) so about 190+ hp so SBD says.
