why is QUENCH important????

I was told and remember reading that a tight quench is important to keep from detonation. Anything from .050 to .035 would be ok. I am currently working on a project that I dont want to buy custom pistons for and found a piston that will work but it sits .105 below the deck. The motor still comes out to 10:1 compression so that part is ok. So here is my question, Why do you have to keep a tight quench???? Whats the difference between this piston and one that is .010 deck height with 22cc dish built in? Either way they both come to 10:1 compression, I just dont understand why quench would make any difference. Both have 10:1 compression, just one has the outside edge higher and one is a flattop .105" low. I have searched all over the internet and no one really talks about it, or explains why.

As long as I have the compression I need can I run with pistons .105 below the deck height?
