Is this the right water pump for an L31 Vortec with Vintage AC?

[msg]

I had purchased a water pump and installed on my 66 C10 but it looks like I bought the wrong one. It only had 1 heater hose port and before I bought this one I was hoping someone might know.

The search was for a 1997 C1500

If that link is the correct one this time, do the metal stems need to stay put, or can/should I replace them with barbs to get the bypass hose to the intake connected properly?

Ill attach a pic of what I have now and the vintage air instructions
