Oil pump 5 hole versus oe 6 hole pump for slant 6

I am looking to put a new oil pump on the Slant 6 225 I am building in my garage. I see the old oil pump is a 6 hole oil pump. All the new ones show only 5 holes, but the gaskets still come as a 6 hole pump. How do I make sure I apply this 5 hole pump correctly to eliminate the hassle of taking the oil pump off the car with the motor in it because of a oil leak from the oil pump?

The reason I want to change out the old oil pump is because when the motor was pulled from it's original car, they left the motor leaning on the oil pump. I think it may have bent the shaft because the oil pump does not turn freely by hand. It binds.

I found this melling 5 hole oil pump and some info on the oil pump gasket on Slant 6 forum. but it doesn't mention the melling and the gaskets that come with it. Or the fel-pro gasket in the gasket set for the slant 6.
