I pulled the distributor and used a 1/4" deep socket on a drill to turn the pump. I now have oil up to the heads. More oil on the left side than the right but the oil is there. Thanks for all of the assistance.

Now I need a set of rockers and pushrods. Wanted ad posted in the classifieds. 

You might try removing the distributor and then using and electric drill, turn the oil pump shaft. That would definitely turn the pump fast enough to bring oil up. You would probably need an assistant to turn the engine over while doing this so the cam turns. Not sure if you have room to do this and obviously you'd have to re-time the ignition afterwards.

By blowing air in,  the pump may have lost it's prime, but it should pick up again. You could turn the motor by hand to place the cam cross hole at the point of feed and use a pump oil can to put some oil back in the system. A temporary mechanical oil gauge rigged up could give you a better idea of what's happening.

Now that you've put penetrating oil in & blown air thru the oil supply holes, how about manually lubing the rocker assembly, & then starting the engine again for a few of minutes to see if you have cleared the problem. (this assumes you have reinstalled pushrods of course)

The drilled cam sounds reasonable because when I was applying air pressure in each oil feed hole the oil was spurting (as opposed to a solid stream) out the opposite hole.

However, when I crank the engine without applying air pressure  no oil is pumped out of the feed holes in the heads. The starter is turning the engine at what I would guess to be 100-200 RPM. Is that not fast enough to pump oil up to the rockers? In other words does the engine have to be turning at idle speed (500 RPM) to get oil pumped up to the rockers?  

It probably has a cross drilled camshaft, so the oil supply to the rockers will be intermittent.  Most likely you will have oil to the rockers when you run it, since you can blow into the oil supply holes and they blow out somewhere.  The rockers don't require a lot of oil.  If oil comes out the overflow tubes when it's running, that means the shafts are full and there is sufficient oil.

what this tells you is that you may not have a grooved cam but a drilled so it has to rotate the camshaft for you to be able to get pressure up.

If it aint broke, lets modify it!

I used a blow gun with a rubber tip to pressurize the oil feed on each side while I was cranking the engine. Doing this caused oil to blow out the oil feed hole on the opposite side. It does not blow oil out if I don't crank the engine.

Is this telling me anything?

Yes, all of the valves popped up when the rockers were removed.

I filled the oil feed hole in the head with PB Blaster and it drains out quickly.

The broken pushrods may be a sympton of stuck valves.  Did they all pop up when you removed the rockers?  Lack of oil to the rockers can be caused by a worn cam bearing, insufficient oil pressure (the light will go out at around 10 psi), or plugged oil passages.
