Well, the sprockets will only go in one way, so you can't mess it up there. Easiest way to see if you got the chain installed right is by aligning dot to dot. Once you got the chain installed, do a couple of full turns to make sure the alignment stays the same.

I would loosen up the oil pan if I were you. I had a hard time putting mine in with the oil pan loose (new gasket) so you get the idea. Others have managed to put it back on without problems but I wouldn't take the chance.

Oh yes, forgot to mention. Dot to dot is #6 TDC. Cam dot at 12 and crank dot at 12 is #1.
