Tom,
I believe the Kill Bleed is also known as a Siphon Break, correct?

The pic shows all 3 E-holes open however I currently have the middle blocked.

What I would like to know is where the 2 E-holes for the 4781 Holley are located relative to typical float level on that 850 Holley?

jon,
I tuned mine for a lean cruise (easily into the 15's AFR) and solid 12.6 at WOT and I want to keep it that way if I can.

I'll flip the pri. and sec. pumps before increasing the IFR.
