Ahh... Now you have THE MAN involved ! ^^^^
What size lines do you have and what reg are you using ? You should call Deano. Danny has great stuff too.

Re: Quadrajet Gasket and tuning
 

Assuming the fuel delivery checks out, the high-speed bypass tubes can be drilled out to richen the top end only. Danny Ashley may have already done this for you, but you should ask if it was done, and if so, to what size.
After making this change, you may need to use leaner secondary metering rods.
