Carburetor Install question

I run a 1" HVH super sucker and it improved my throttle response and evened out the fuel balance. #7 cylinder is my leanest and required secondary split jetting for even WOT 1/4 mile.
It takes a lot of testing to compare spacers and get the jetting right every time you swap to a different setup IMO. I ran no spacer, 1" open, 1"4 hole, 1" HVH 4 hole and the HVH is the best for my combo (340, eddy AG, Demon 750dp).
