I have a new head torqued on and cam is at tdc but the crank is 90 degrees off. Do I have to take the head off again to put the crank at tdc because of interference, or can I just hand crank it with it on?

Take out the spark plugs and rotate the crank towards tdc until you feel the valve touch the piston, do it really slowly and apply minimal pressure. Once it touches rotate it the other direction slightly about 10 degrees and rotate the cam in reverse till you get it lined up.-E30 323i 1983
