G9 knock and no spark

These problems may be related but I don't see how. The no spark problem was the spark plug cap it was open and should have 1 K resistance. I replaced the cap and it tried to run but back fired some and just could not get any RPM's.
I pulled the valve cover ans saw the exhaust valve was not moving. I pulled the engine yesterday and couldn't find my clutch puller until this morning. I pulled the clutch and side plate and found the cam shaft broken in two pieces.
I assembled this engine from two so I think an assembly dimension was too tight.
I did not use a gasket on the side plate. I used aviation form-a-gasket which may be problem but I don't think so. I am trying to align the cam and balancer now but a lack of timing marks is causing another problem. Please give me your thoughts on this matter.
