IFR and Air Bleed sizes?

mopowers said
More Holley tuning questions. I need to procure some tuning parts to cure a couple minor issues with my Proform 650 DP. Specifically, I need some idle feed restrictors and assortment of air bleeds. Is there an all-in-one kit you folks can recommend, or is better to buy the blanks and drill my own?

I do have a complete set of pin drill bits and a pin vise, so drilling isn't a problem. Does someone sell the proper blanks, or is best to go to mcmaster-carr or somewhere similar to obtain the blanks. Lastly, what sizes will I need? I'm assuming 6-32 for the IFRs and 10-32 for the ABs. But what length??

Thanks!

You can get blanks from Quick Fuel or Holley or a dozen places. I get mine form McMaster Carr because my metering blocks won't take a flanged headed bleed. You are correct on your sizes.

If you have a lathe you can take a piece of 1/2 aluminum and frill and tap one end 6/32 and the other end 10/32. Then just screw the blank in and drill it out. If you don't have a lathe, you can have someone make you one and do it in a dril press.
