Degreeing a Cam Shaft

Gentlemen (and ladies), I finally got the tools and a set up that can produce repeatable results. However I still have some questions.

It took me a little longer than Id like to admit, but initially I dont think I was matching the crank pulley's keyway marking with the indicated one that should match up with the "O" mark (there are no other indicator markings on the cam shaft gear) on the camshaft gear. But once I figured that out I determined through following my process mentioned in the beginning of this thread I needed to have the key way in the 4A slot (4 degrees advance) and the crank gear marking 4A line up with the "O" mark on the cam shaft gear. That produced the following results:

Opening at 3 degrees BTDC (cam card says .050" lift at 2 deg BTDC)
Closing at 37 degrees ABDC (cam card says .050" lift at 72 deg ABDC)
max lift coming in at 108-109 degrees ATDC (cam card says max lift at 109 deg ATDC)

Now, my timing set only allows the flowing adjustments:
8, 6, 4, 2 degrees retarded
0 to 0
2, 4, 6, 8, degrees advanced

So my question now is, where do I set it up? It appears my opening is almost within spec and the max lift is coming in at where it should, but my exhaust is closing 35 degrees before it should. so what is more important? intake opening? max lift? or intake closing? it would appear the duration of this cam lobe is off from what the cam card states.

Now, if (thats a big "IF") I initially installed the cam shaft correctly the markings were originally 0 to 0, which means my cam was 4 degrees retarded.
