OP asked how should he get more cr and he gave a few options, mainly..
A. KB pistons
Or
B. Heavy milling
And I said I prefer A. especially if there's a possibility of upgrades down the road, if there's zero chance of upgrades I could see going B.
Apparently to you, only an idiot would give that answer.
Then you seemed to take offence that I said proper pistons instead of aftermarket and that I said the KB's would have more piston to valve clearance, apparently I'm wrong and zero decked stock pistons obviously have more p/v clearance lol.
