thats why i was asking about how you did it so you would explain
Now putting oil in the cylinders was going to be a suggestion because of the very thing you mentioned, if the engine was out for a long period.

The other thing is that cam gear problem, if you happened to install it wrong the first time (180deg out), it may have bent some valves, that's why it didn't want to run and why it wont run now even after changing it, and compression is down on all the cylinders like it is. That is a HIGH possibility. I could be wrong but based on your description and new information i would take an educated guess and consider that as a strong possibility.
Do the oil trick first, if it works then awesome! if not and there is no change i think you'll be pulling heads next.
