>>>engine turned to where I though TDC was<<<
NO!!!
It will have both valves closed, but on the overlap between Ex closing and In opening.
You need TDC on the compression stroke and that ain't it.
Two years ago when this thread started, you could have said the cam was 180 deg out. You could pull the cam out a little and turn it 180 deg. BUT!! Why not just turn the crank 360 deg or one full turn. If the two marks line up, the only thing that can be 180 deg out is your thinking.
