Thankyou Bob Donalds
 for the correct diagnosis that the valves were indeed siezed in the  guides
because of fuel contamination!
I removed the heads and with carb clean and a torch (not at the same
time)they are now spinning freely again.
The intake runners were literally filled a .5"   with what looked  like
roofing tar!
Heads are cleaned and back together valves lapped in and look great, guides
are spec.
Now ...back to the fuel problem I was trying to get around earlier!
The lesson here is when you get a van that has been sitting. Do some
preventitive service.
I actually drove this thing around for a while before this happened!
Now I will clean the tank ,change the brake fluid ,and the rest of the
fluids too!
I am glad I did not fly across the country and think I would drive this
thing back or I would be doing all this on the side of the road!
lessons learned
