You listed the wrong carb, look up a 500 CFM AFB (performer series).
"Comes with: Metering Jets - Primary .086, Secondary .095; Metering Rods - .065 x .052; Step-Up Spring - orange (5" Hg)"
This is incorrect, I spent hours last night chasing my tail due to it.
The listing I posted is for the dual quad calibrations, if you aren't using them in that configuration, my bad. The performer and thunder avs carbs show the same single quad calibrations. In the Edelbrock carbs they are only different in the secondary actuation. That is not the case in the original AFB/AVS carbs. I found this out the hard way. Anyway, good luck with your project.

If you *looked at the link* the information you quoted was for the AVS carburetor, not AFB. AFB while similar are NOT the same as AVS.
From the AFB page-
Quote:
EDELBROCK PERFORMER SERIES 500 CFM, MANUAL OR ELECTRIC CHOKE CARBURETORS CALIBRATED FOR PERFORMANCE
Designed and calibrated for small cubic-inch engines such as 305 c.i.d and smaller Chevrolet; 302 c.i.d. and smaller Ford and dual-quad applications such as Edelbrock C-26, F-28 and Street Tunnel Ram. Match with an Edelbrock Performer or Performer EPS manifold and other brands of similar design. Includes both timed and full vacuum ports for ignition advance. Comes with: Metering Jets - Primary .086, Secondary .095 ; Metering Rods - .065 x .052; Step-Up Spring - orange (5" Hg).
The page is wrong.

I've tried to help as much as I can, so I'm done
And taking one for the team.....
I appreciate the link to Edelbrocks site, don't know why its so hard to grasp that Edelbrock has the listing wrong for the AFB jetting.
Verified it today by driving around with the O2 gauge operational showing the correct air/fuel mixture with the the larger jets on the primary side, as it should be.
Must be a Holley thing ;-)

I'm going to this up, with better data. My combo- 406" B engine mildly ported RPM heads 9.7:1 cr, Comp Cams thumper- the baby thumper 227/241 .518/.504" lift with 1.6 rockers 107lsa and a Offy tunnel ram. The previous jets listed were VEERRRy lean. The final jetting ended up .92 primary .89 secondary .52/.62 metering rods.
Current jetting is .95 on the primaries with an old set of .60/.70 metering rods and .83 on the secondaries.
With the O2 gauge this is very close with some minor tuning needed with the metering springs to dial in the cruise a touch better. Car just screams to beat the band now, rear gear change coming up next.
