Default Dual Quad 428 CJ

Hey all, I'm new to Club Cobra and just recently discovered this forum. Really enjoy the read.
Was wondering if someone could help me with this combination. The intake is a C7ZX off a 67 Mustang Shelby GT 500 428. The carbs I'm running are Ford P/N 5752426, which are 600 CFM units, basically 1850s. I'm running #60 jets on all corners and it works great. My problem is a rich idle. Running in my garage it burns my eyes. I've tried everything I know but can't seem to lean it out enough.
Power valves are 6.5

Additional info is as follows:

Cam - Comp Cams, Roller, 282/288 adv duration, 521/532 lift.
@ 0.050" 230/236 deg duration
Lobe sep is 110 deg.

Anyone have any ideas?
