What am I talking about??
What are YOU talking about?
"My old motor seized, and I'm re-using the head off it. The head is an N47, came off an N42 block, gonig back on an N42 block.
The problem is that the motor didn't seize at TDC (wouldn't that be nice) and I have no idea how to get it back to TDC.
Any help?"
You're saying here that you want to turn the frozen motor to TDC. What I figure you meant to say is you need to turn the HEAD to TDC before installing on "new" engine. I was explaining how to do that.
Read what hainz said under his vid, same thing. Semi install the head with engine at halfway tdc, as in pistons in the middle, so you can turn the camshaft to TDC (cams at 11 and 2, notch on gear aligned with plate on cam tower) without hitting the pistons. Then return engine to TDC so you can install the timing kit.
