Holley ultra hp 750. It is a little rich but not terrible.

Made a few more pulls. Basically the same numbers. 

Tried adding a 1/2" open spacer to lean it out and see what a spacer would do on a dual plane. It picked up a little hp, lost a little torque and leaned out the mixture to some better levels. 

Probably could take a jet or two out of the left side to even the air fuels out

Is the engine internally or externally balanced? Has a stock appearing, painted front damper is why I am asking.
