What is it going in, weight? Your intentions?
With that cam and those heads you should be higher in compression. I would run the stock Z06 gasket. It should be a pretty stout build. I would call either Jon or Jason as TSP and they'll set you up with something pretty good. I just ordered mine from Jon and is about the same build, I used the LS7 heads instead of the etps.
Your static compression doesnt really matter as much as your dynamic. If your dynamic is aroun 8.6 you should be fine on 93. I had a DCR of 8.8 on my 403 and a static of 11.5 and i ran 30 degrees of timing all day with no problems. With that cam you should have no problem on pump gas.

If you are in teh area of 12:1 that cam would probaly be right. 250 ish @ .050 with .6xx is the target area. I personally would run a bit more lift than what you have listed, like in the .650 range, but I like lift 
My 414" is 12:1 and I am hooked up on a solid roller in teh 260/270 range with almost .800 on a 110 (and when I say almost .800, it is in the area of .750/.760)
