You'd have to dial bore guage them, but they will almost always leak a lot more than if you bush them...

Kind of wondering about the accuracy of the machining. I have heard stories about how Petty Enterprises actually cut out the lifter valleys in their Cup motors and repositioned them to 1) get rid of the 59 degree lifter angle and 2) get them all in line and on the same angle.

I would imagine the shops that have the tooling to bush the lifters would be able to get them all in line and installed properly.
