This is a great thread. Props to AMS for taking the time to do this testing and share the information.

Maybe I am missing something or have a misunderstanding of cam timing. If so, please share to expand my knowlege as well as that of the EVO community.

The way I understand it , a number of variables affect how much you have to adjust the cam - i.e. camshaft, crankshaft, timing chain, sprockets. So to assume that the crankshaft, timing chain, and sprockets are exactly the same from engine to engine would be a stretch, IMO. That's why I said that even if Martin were to tell us how many degrees he had to adjust each cam to get them to be "straight up", I would not take that number as gospel and apply it to my engine - even though I have almost an identical engine build to Martin's Evo.
That's also the reason why, when I have a set of cams installed, I try various cam gear settings to see where the powerband works best for what I am looking for. Using that method I also don't have to worry about degreeing the cams.

Eric,
Waiting on this information, but which style of Tomei cam? And do you think me changing from JUN 272's to the Tomei 280's would be worth the money? This is why I wanted to see the JUN so I could compare to the Tomei.
Need more results!

The Mitsubishi Lancer Register has some good information regarding different cams. I am not sure how accurate this information is.

So which cams is the best for stock head w/37R?

more results FTW .... c'mon, c'mon ... I know you guys couldn't possibly have anything better to do. 
Those Tomei results are very intriguing, but I still wanna see the mythical cam that will improve over my HKS 280s across the entire powerband...

If you could update the first page with the daily Cam Tests that would be gravy, this way we don't have to wast time shuffling through pages looking for the results.. It will also be easier to compare all the cams being that they will be displayed on the same page.
