Need lots of help!

I am putting a rebuilt N42 head on an L28 (79) and am having some issues. First I can't get the cam sprocket back on, I've read all the posts about this problem but have another problem to go with it, namely I believe the timing chain slipped about 3-4 notches from where it needs to be to maintain the timing. Short of pulling the front cover is there any solution? Other questions, if I have to pull the front cover do I need to take off the oil pan? Can the dizzy and oil pump be left on the cover? I've read lots of stuff about pulling the crank pulley but nothing about putting it back on. Any good ideas on taking out the crank bolt with no flywheel in place, just the bolts? The engine is sitting on a home made floor stand, but lifting it up is no issue it its needed. I used the wooden wedge when I pulled the head but obviously I screwed up somewhere! Any help will be greatly appreciated. I've spent the last 3 hours reading lots of posts about cam issues and front cover stuff but am still stuck. Thanks.

I think you would be better served to pull the cover. Since the engine is on the stand, pulling the pan would be easy. Do remove the oil pump and distributor. You can clamp or jam the flywheel whilst removing the vibration dampner/pulley. You can then inspect the tensioner and chain for wear. It's a LOT easier to do this since you have the engine out of the car.
