The holes do matter, one is marked for evos and the other is for dsms. Use the wrong hole and you will be a few degrees off. If you don't believe this, go compare a stock dsm gear and stock evo gear, the tdc mark in relation to the hole is slightly different. Fidanza had 2 holes on the gear for a reason, ask someone there who is knowledgable.

I just checked the gear differences on a dsm engine. I set the stock dsm gears at tdc, locked the cams in place. then swapped in a stock evo gear. Everthing still lines up. So my above statement is incorrect, and the techs at fidanza are correct. The two holes in the gears are simply 90 degrees apart. Since there are 48 teeth on a gear moving the hole 12 teeth is not an issue.
What is nice about this is you can use dsm cams in an evo or visa-versa. You just have to move the timing marks 12 teeth to the left or right depending on which switch you are making.

thats what i figured. i checked mine out last night because i was in fear of them having the timing problem like the one from post 1 (which they don't. i also used a level surface and a level to check that they were true which they were). the tdc mark above the evo hole is 90 degrees off from the timing chart. it shouldn't matter what hole you use as long as you set the timing via the chart

Why dont people just degree thier cams? Seems that would solve any problems associated with this anyways. Also, as for the gears whining, wiggling or vibrating. I had the same thing... this was the result:
