Default Holley jetting

Running a Holley 700 DP. Motor is 351W +.030, 9.5:1 CR, TFS's out-of-the-box heads, Perf RPM intake, Comp Cams Hydraulic Roller 224/224. Typical street Cobra motor.

Stinks and burns your eyes when running in garage, even with door open so I know it's running way too rich with out-of-the-box jetting. Primary jets are #69's. I'll drop it two steps at a time and likely go to one of the local emissions check places to check my AF ratio till I get it dialed in.

Off the top of your head, what jet sizes have you used on combos like this?
