Adjusting my carb to my new heads

I have used two Proform center body's, (780 vac. and 800cfm double p.) and both came with #72 F. and # 84 rear jets, so the jets are 10 to 12 sizes apart. You can also look up on the Holley site, the jet and bleed # for every carb. then you can try their tuning.
Choke plate doesn't mater. I even sawed off the choke horn on the 650 DP. Then I used the parts on the Proform 800DP for my 440.
The 340 got the Proform Vac. secondary it uses #71 front, since it has the drilled out PVCR. The back is too rich (sooty exhaust pipes) / #86, so the #84 are going back in. The vac. spring is purple, after many tries. It now runs 12.94 et on 275/60 Kelly street tires, and 3.90 sure grip, see my video from Sonoma Ca. I tried colder N9y and it lost one second. Back to the n12y plugs.
