Am I correct in thinking there is no way to make my timing 180 degrees off without taking the head of the block? With the t-belt off I am sure I could force it but just rotating normally by hand it wouldn't work, right?

I suspect that you could not even get the head to seat with the timing 180 out. I know you can't rotate the crank 180 with the TB off.
Is it possible that you are being confused by the fact that the cam turns at half engine speed. That means that both marks line up every other revolution of the engine.The car makes it possible, but the driver makes it happen.

Yeah, I know the crank lines up twice so I thought it could happen.Comment

Not sure what you are trying but you can rotate the crank or cam as needed but do not FORCE anything! If you are turning the crank and hit resistance turn the cam some and you should be able to continue turning the crank or opposite if turning the cam. If turning the cam don't let the valve springs rotate the cam while rotating it.Comment

interference motor. If you forced it that could mean bad news.Comment

the crank lines up twice because the cam turns 180 for every 360 of crank movement. You can't have the head 180 degrees off in crank degrees, but you could have the head 180 degrees off in cam degrees.
In any case, if it lines up it lines up. The head doesn't care how many times you've spun the crank, TDC on the crank is always the same - it's the cam degrees that matters.Comment
