OK, so today I started out trying Skippers recommendation to supply shop
air to the head and see what happens.  It blew air out of the cam cap oil
holes but that was about it.  So I tried a quick and dirty thing of pulling
the one head bolt that supplies to the oil to the head (behind the coolant
flange) and blowing air through again.  I got some black goop out of the
hole but air did come out of the head and into the head bolt hole.  So I
put the head bolt back in, retorqued it and started up the engine.  Still
nothing.  Oil pressure at the base but nothing at the head.  Shut it down
and pulled the head completely.  It appears that someone used some either
black RTV or heavy black grease on each head bolt where it went into the
block.  I am guessing this RTV is what was sealing up the bolt and not
allowing oil to come up into the head.  Tomorrow I am going to spin the oil
pump over and see if oil bubbles out of the oil supply hole in the block.
If it does then this should confirm my RTV blockage theory and then I will
have to try to clean it out of the hole and hope that it will fix the
problem.  I spoke to the company I bought the motor through and my salesman
didn't tell me but he went away on a vacation trip today and isn't going to
be back until next Wednesday (nice).  I talked directly to the boss and he
says he is going to try to help me out.  We will see.
