Are the jets in the primary and secondaries the same on a holley 670 avenger? Do they interchange as long as they are the right size?

I've had two 670 avengers and neither had the same in the primaries and secondaries. In fact I've never seen the same jets in the primaries and secondaries of any Holley unless you plug the power valve. My 1st 670 had 68's in the front and 72 in the back. Just got a brand new avenger last week and it has 68's in the front and get this, 89's in the back. I first read through the papers that came with it and noticed they said it had 89's in the secondaries and thought it must have been a typo so I took the bowl off to check and sure enough it's got 89's in the secondaries. That's more the size I'm used to seeing on a 870. I'm gonna call them tomorrow to see if that's a screw up cause it don't sound right to me. I also checked the air bleed sizes to see if they changed that because that will affect the jetting some but the bleeds are all the same size as my older 670.

I think Rob was referring to them being the same thread size and not jet number. In other words you can pull the primary jets and put them in the rear.
