Sure. It gives the engine just that much better of a chance to start up w/o being starved for lubrication for even a couple seconds.
You want to rotate the engine about 1/4 turn at a time as you prime the pump so all the lifters get oiled. You'll know the lifters are oiled when oil comes out the tops of the pushrods at the rocker arms.
When you use a tool to prime the pump, be sure it has the section that connects the two sides of the lifter galleries (that's the blue piece at the right side, in the photo below). Some auto parts stores will loan this tool after you leave them a deposit. Using an old distributor w/the teeth ground off the distributor gear also works fine for this (shown in the thumbnail below).
