Hence firing with valves open?? I then barred engine over with ditributor on until inner rotor was pointing at about 11 oclock atthe #1 tower on inner cap I had previously marked the distributor housing inside to assure rotor would be pointing to it and checked valves - #1 intake was open - it appears the cam / dist "sync" is out about 45 degrees?? Is that possible??

You must also make sure that timing mark on hub of cam (usually a line) is lined up with timing mark (also usually a line) on steel insert that is molded into the ID of the fiber gear. As someone else mentioned, the timing gear could have slipped on what's normally a pressfit on the cam hub.
