Default Plug size for heater hose holes

Hi

I have a 75 stock vette, and I going to remove the heater hoses & plug the hoses.

What thread size plugs to use on the water pump and intake holes.

Thanx in advance

Allen,
I would take the old inlet fitting to the hardware store & match up.

They are definitely two different sizes: 1/2" and 5/8" (I think) pipe thread.
