holley 4150 carb issues and questions

I only pulled heads and did not check cam numbers when I got engine.
As for compression I also didn't check that ether. Was told 10.1 but I'm not %100

Car idles fine, has that lumpy idle and pulls @8" vac. It has 6.5 power valve in front and blocked in rear.

I want to say 76 main jets and 80 rear.

I had vac hooked up but it is now blocked.
