Been there...done that!!!! After pulling the motor on my orange COPO after spending hours to install with no chips or wrecking finishes on bolts, I now have a new engine guy who pre runs the motor and breaks the cam in on outer springs only to make sure it's right on. We then dyno it with many pulls to 6000 rpm (7000 in the ZL-1 case). When it goes in the engine bay, it's READY!!!!!! Best $350 bucks I ever spent!

You hit the key note, it is mag. and pressure testing. A reputable shop should know to pressure test big block heads after a new Guide(s) has been pressed into the head.
