Now for the original question.
Get a pushrod length checker.
Some lifters are known to have a different plunger heights (even OEM GM units vary).
Example:
If the heads are not shaved and your set of lifters have taller plungers, then you would end up needing shorter push rods.
If the plunger is lower/shorter in the lifter then you would need longer push rods.
It's always best to check for piece of mind -vs- having a bad rocker swipe and shorten the life of your valve train.
