That's way off.

Your jetting spread is nowhere close to correct. With PV's the jetting should be squared up front/rear. You have a 13 step spread. I'm guessing you are lean up front and rich in the rear

If you have a power valve and remove it, you normally jet that side up between 6-8 steps

That carb, if it's a 80496 should have 78's front and rear with a power valve in each end. If you remove the rear PV, then up that side to around 84-86. Start there and tune it up.
