Thermoquad race tune

Hey everyone. I have a thermoquad that I am going to try on my 340. I have a few that I can rebuild.

6318- 73' 340 MT 1-3/8"
6324- 73' 440 HP 1-1/2"

The 340 is currently a mid 13 sec car (4 speed w/ 3.23s) with a 750 Holley Vac. secondary.
(1970 340, 10.5-1 comp, Lunati 60403 cam, LD340 intake)

I was curious if there are any tips for race prepping a thermoquad. (jets, metering rod # etc.) Any first hand insite will be great.
