I had the same experience with the Holley jets. So I have been buying all of mine from Quick Fuel. They are usually cheaper than the Holley jets and I have found them to be right on size. I measure all of mine right out of the package before I put them in to make sure. Quick Fuels are exactly what they say, a 70 is a .070" and not a .0735" per the Holley chart.
Sorry, I have no experience with the max jets.
