Default Heater Core outlet plugs for water pump?

Finally worked up the guts to turn the old Z into a real street/strip machine, and delete all the crap that isnt needed. Now with the AC/heat gone, I have two outlets on my water pump I need to cap. Whats the best way to do it? There different sizes so I cant just connect them, any ideas?

You can either use caps, pull out the fittings and use a freeze plug, or have them welded shut. Those are your three options and in the order of least expensive to most expensive.

I pounded the fittings out and had a machine shop plug them up. It wasn't too expensive (like $30) and looks clean/professional.

You could also take some heater hose and run it in a loop from one of the heater fittings to the other. That will work fine but look a bit more ghetto. As far as caps, I'm guessing ramair means heavy duty vacuum caps that will go over the fittings - then hose clamp them down?
