Typically if you had a .015" High Speed Air Bleed in the 4 positions (Primary and Secondary), you would have the same .015" High Speed Air Bleed in the 4 positions (Primary and Secondary) on a E-85 Carb.

If you had #92 Main Jets in all 4 Corners of the carb with Gas you would also have #92 Main Jets in all 4 positions (Primary and Secondary) on a E-85 Carb.

Now the Idle Air Bleeds are typically .070" on a 850 Holley Gas Carb and they might be in the mid 50s range on a E-85 Carb.

And with a High HP E-85 Carb the shooters could very well be in the .040"+ range to get the Accelerator Pump right.

With a E-85 Carb or a higher Boost Gas Carb you will need at least 4 Power Valve Channel Restrictions.

That being said, in 90 times out of 100 with a C&S carb you will be very close right out of the box on a typical Pontiac Engine with Boost. Dyno Testing is really the best way to dial in a carb for the Power side of it.
