You should have some pipe plugs in the head and waterpump. Head location is on top about 2/3 of the way back and off center toward the manifold side. They may be regular pipe plugs with the square head or may be sort of flush and have a socket for an allen wrench. IF plugs are original and have never been out they have probably rusted so it may be a real project to remove them.

Once removed, you are going to have to find a valve for the head and a nipple for the water pump. Universal shut off valves are available thru most parts stores. Not sure about the nipples. Should be 3/8 NPT thread into the head and pump with 5/8 hose fitting but you do need to verify your thread size.

The Universal valves are short with the hose coming straight out the side compared to the originals. You may also need to get a male to female 3/8 pipe extension to raise the valve a couple of inches so the hose will be sufficiently above the manifold. Some have said a valve more looking like the originals can still be found at some plumbing supply places.
