4 Barrel on a stock slant

I happen to be working through this right now.
225 inch engine, 9.5 compression, RV cam, ported head with stock size valves. Hooker long tube headers, Offy intake.
Carb is a 600 AFB. From what I am determining, the carb itself is an ideal size for this engine, but the stock jetting was drowning it.
I keep taking fuel away from it, and she keeps running harder. .98 jets on the primary side, with original drop rods (stock was .103) and I'm down to .081 in the secondaries (started at .098)
Very happy on the front side of the carb, but it looks like something in the mid .070s will be perfect on the back side.
Running the car this weekend, so should know soon.
BTW, not set up for the street at all, but running this car around the industrial park by my shop, she is an absolute kitten. Drivability is excellent, and with the small jets, full throttle roll-ons are smooth and clean.
