I have always had problems with quick fuel and holley larger needle and seats. If you don't lap them they never seal. What I have done is switched to blp titanium n&s for all my builds. The .140 is perfect for e85 carbs. That is what I use on the majority of builds. I will go bigger when the demand is there for carbs over 1250 and up.
I am having the same dang thing happening with my quickfuel 950, thats why I was thinking about letting you do my dominator at some point. can you explain lapping them in? are you talking about the needle and seat bore?

i have simular problem on a dominator with BLP .160 ns. 7psi or more and they dont seal, but i should be fine with 6psi anyway.
With the 160 I wouldn't think you would need much over 5.5psi. Unless fuel demand are extremely high on your combo. With the 140 I normally run 6-6.5lbs at the most.
