I personally like 105s with cams, they work for the vs, xp, and s1x, going bigger and you'll want 130s or 150s depending on the cam. Nothing wrong with the 90s it's just a personal preference.
I had a machined gear on my double roller and ran 2 gaskets and it still rubbed on one of my covers with the turbo cam. Now this may have been installer error since it didn't happen with my xp or is3 cam setups, same double roller was used with all my builds. That being said if I were to do it again I would have it machined, use a machined oil pump cover and use the thicker gasket just to be safe. Is it needed, no, but I'd rather have the extra room.
Don't forget the oil high pressure kit if you don't already have one.
