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.

If you are on pump gas, I would not really go over 11.5 or so on the compression..

Pump gas here with 12:5 compression and 24-26 degrees of timing in the last build.

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)
