If you buy a carb spacer, you can run a box stock holley on a rotary without having to do all the RB mods. Those triangle air cleaners are $20 from Summit racing.
Also my package deal comes with a Holley Pressure Regulator, Fuel Pressure gauge, new manifold, new carb, the secondaries are mechanical and not vacuum.
When you price everything:
Holley Carb $300.00
Manifold 250.00
Holley Air Cleaner 20.00
Holley Fuel Press Regulator $33.00
Okay... I will take $ 600.00 plus Shipping

the key thing here is if you are going to use a holley, then you need the 4150 series to be able to fully tune. and hell, even on that the air bleeds are "pressed in". get a dominator for even more options, but it's not neccessary. any 4160 will be very very limited in how much power you can get out of it. for a basic "cruiser" yea it'll do just fine. but if you want power get a 600cfm 4150 model DOUBLE PUMPER <...... that is key. ahhhhh 
and like someone said earlier, you do NOT need to do any mods to make it run good on a rotary. hell i never even used a spacer.

If you want the Holley to run sick on a rotary you should run the Weber Powerplate in both the primary and secondary circuits. I believe they used to be made by Edlebrock or some American company. It basically removes the Holley jet system with two plates, one holds the complete Weber fuel system (air jet, emulsion tube, main jet, idle jet and holder) and eliminates the powervalve. I ran one on the primary side only which made it much more driveable and SO MUCH EASIER to change jets....you can change the airs, emulsions, and mains while the car is idling...no problemo. Running on both primary and secondary will give a **** more power top end. It also killed some of the shitty fuel vapor smell you get on Holleys.
The problem...hard to find and kind of expensinve...like $250 each. But if you are a diehard 4-barrel fanatic...its the only way to go. There's a few with Albert at Rotary Engineering I believe plus the guy I sold my Holley to....ask around I guess.
That's why I went Weber IDA and won't ever look back to the Holley.
