The only real possible "issue" I see is the stock rockers. What can happen with those when you start running high lift cams with elevated spring pressures, they can fail in the pushrod cup area. Especially ones that already have lots of miles on them.
Since you'll be putting a lot of mikes on it, I'd stick with cams that have some more moderate lobe designs and limit the lift to .500 or less.
You could look at the cam grinder of your choices catalog and pick something out pretty easily.

Most of the cams mentioned in the 440 smogger cam thread would also apply here, although an lsa of 112 would be as wide as I would suggest for your build, preferably 108-110.

I think I'd use something like the smallest Howard's Rattler.
