not sure what you mean by 0cc...when you cut valve reliefs you are going to create some "+ volume". are you aiming for some specific compression ratio?

I think he mean true flt top pistons.

Just get the Diamond -2cc pistons & call it good. There is nothing wrong with a little bit if extra PTV clearance. And your not gonna lose very much in the compression area with the -2cc pistons either.

I'm telling you man, get the -2cc pistons. You're getting the MS4... that's a big cam, you'll want the extra clearance. Trust me.

Probe Industries sells a 3.902 piston flat top w/3cc reliefs and a 1.315 c/h (6.125 rod/3.622 stroke)

Can I ask why you want the flat tops so badly? You really aren't going to loose much power at all with the -2cc's, seriously. I really think that it's a better choice with a cam as big as you're going with.... but if you're stuck on the flat tops then it's your call.

Because i don't want to lose the CR , i calculated the CR with 241 heads and -2 its will be around 9;9;1 , right ?

Just mill the heads down to pick-up the compression. Stick with the -2cc pistons for the valve clearance.

how much i need to mill the heads ? to pick the CR to 10;1 , how much the maximum can i mill the 241 heads

Just mill them .030" On that head it will give you a 59cc combustion chamber. you should keep your CR as high as possible if you plan on nitrous. Nitrous loves compression. But if you mill at all you'll need to get the -2cc pistons no question. You should get them anyway, they aren't going to hurt your CR enough to even notice. There's not reason not to. None.
