I just picked up a project car 1992 525ia with blown head gasket. This will be my first head job. I do most of my own work on my e39 & e32. I feel like this is something I can do.

Anyways, is there a good write up about the head job. I have been reading a lot and everyone isnt clear on the tool to lock the cam or not. I know u need to align it at TDC ON CYLINDER 1. Any info will help. Thanks
