SB Crane Retrofit Roller Lifter Issue

Why not prime the motor with the intake off to see if there is any leakage?

I'll definitely be doing that for sure. Right now my block is fresh out of the machine shop and bare so I don't have enough parts on it yet to run the oil pump. I plan to run the pump and turn the motor and watch the lifters to see what happens. Should be ok but I'll be checking any way.
