Rudimentary valve clearance question.

I am considering the comp cams xe solid .520 and .540 with 244 and 252 or the .525 .525 with 248 248. Yes I'm using a .040 gasket because of zero deck and not a steel shim. These cams were also what the comp techline recommended. I guess it's a 119.95 gamble, but I'm pretty sure of my readings since I did find the closest points were not at max lift just like you said. I also did get the exact same readings over a two day period of time checking several cylinders.
