How do you prime the oil pump?

Turning it over alot wont harm the cylinders or anything?

I bought this motor as a shortblock to replace the 4.7 in my truck. Added a 6.1 oil pump and 6.1 cam/timing set and am about at the point of starting it, but this is the part that has me worried.
everybody is used to the external stuff lol...so i am lost.

I guess i would have to use a scan gauge to check for oil pressure?
