Retune my entire carb after installing new heads?

I am not sure a fixed orifice is the best thing, because it may be too big at idle but still too small at wide-open...

I found my carb log with the most recent settings: (pri/sec)

IFR .028/.028
IAB .078/.079
TSR .074/.074
MAB (HSB) .026/.026
MJ #71/#86
PVCR .066
PV 7.5"

Tomorrow is supposed to be a nice day, hoping to get the Dart out and get a few AFR readings at low-speed, high-speed cruise, and a very brief WOT on all four barrels :o

Since the head swap, it's a little too lean at the start of the transfer slot (that small flat spot JUST off idle is now worse and leaner), but highway cruise at 60-65 mph is good and lean (15-15.5:1) without surging. I may need to open up my TSRs a little bit.

Depending on what WOT looks like, maybe go up two sizes on the secondary jets?

Hey @Mattax are you around? I've also posted on racingfuelsystems Holley forum :)
