Street 650cfm Double pumper Jets?

I'm looking for opinions on jets and accelerator pump discharge nozzle sizes.

I'm running a stock 360ci Magnum with headers and rpm air gap intake. I'm running pretty rich right now and want to lean the mixture out a bit lessen my fuel dump and wasted fuel out the pipes.

Not sure the Jet sizes int he Primary or the Secondaries yet (On the car currently). My Discharge nozzles are *31. I've herd from a few people in my area that have small blocks and 650cfm carbs, who are mostly running *65 primary jets and i would assume *68 in the rear.

I'm wondering what you've all done to your carbs and whats worked best for you so i can get a general idea or a direction to start doing my tunning.

Thanks!
