Your only going for the orifice size. I never tried but if they fit its only an air restrictor.

Holley air bleeds and main jets have a different thread size/pitch.
Also, keep in mind jet numbers don't indicate their drill size. I.e., a 75 main jet has a .082" drill size according to my holley chart. Whereas air bleed numbers match their drill size I believe. So a 75 air bleed would have a .075" drill size.

We used to epoxy the bleeds if needed, , then drill to suit.
There was a kit you drilled bleed, there were misc wires you inserted into the holes as restrictions to figure which drill size as final, re-epoxy, drill to size.

Very foolish trying to use non-precision jets for air bleeds. Especially the main air bleeds because they are usually very small, 0.030" or under. A small error here can make a noticeable difference to airflow that could he hard to workout as being the culprit, if the engine was not behaving as expected.
No. Main jets are not the right thread size. They are entirely too big. Use the correct air bleeds.

Foolish, lol, - when there was nothing else, you did what was necessary, - not,
Geez, - you can't buy it, so it can't be done . Lol
In this case, it cannot be done. Main jets are 1/4x32 thread. The area where the air bleeds press in or screw in is probably less than 1/4.

That's why I mentioned epoxy.
Epoxy jets on right over the venturi? I don't think so, Tim.

Nothin wrong with epoxy. It's used to shape intake runners/ports for god sake.
Well tell me how you epoxy a 1/4" main jet into a 10x32 thread hole? Huh? What? Yeah. Yall go right ahead with that stupidness.

Who said anything about doing that? Quit being a bonehead and read post #4. Catch up.

I ordered them through Summit. They were relatively inexpensive and I got them in a couple of days.
