Gallons per hour is a complete non-issue provided you have enough. 80 to 110 gallons per hour is probably about two to three times the amount of fuel the engine could burn; unless you're dealing with restrictive plumbing, you've got PLENTY of fuel delivery.
What the carb cares about is fuel pressure; and I suspect that 8 psi is higher than a Q-jet would really prefer. OTOH, if the fuel pressure isn't causing you problems--nothing succeeds like success.
