What should I expect with this 308 combo?

I'm finishing up on my VH with running gear to be done and put in soon.
I'd like to know what I should expect.

When I talked to Malcom at Camtech, he suggested a tight LSA cam grind but I didn't really understand why. (my kids were driving me crazy!)

Any comments?
