Funny, I was thinking about hat mark today as a result of your post.

The mark on the HB is pretty much only for assembly, as the the HB 
shifts over time (due to the rubber bushings) and the mark becomes 
irrelevant.

You *have* to use the flywheel marks to time the crankshaft.

 From teh port side of the car, looking at the tranny, there is a hole 
that lets you see the flywheel.  At TDC, the funky edge thing on the 
hole lines up with a stamped "0" on the flywheel.  Usually at some 
point, when we can, we mark it with a bright paint pen or some such to 
make it easy to see.  But, it is there, roughly six degrees behind the 
six degree advance mark.

it might be hidden by crud, but clean the area and you will find it.

Do you have all the bolts out?  A couple are hard to get to, and require 
lining up the flywheel (darn it, there it is again!) to get to them 
through slots that are machined into it.

If all fasteners are out, parts that seem "stuck together" can be pried 
apart carefully.  Clean well before re-using.
