im really bored off my *** and cant sleep, so i was playing on cspeed what my compression will be. has anyone ever CC'd the valve face(s)?

maybe im doing this all wrong (probably) but you cc the head. cc being cubic centimeter right? so staring at a valve for 5 min, it occurs to me that could be roughly 1 cc. now taking that and subracting it from the chamber volume, and assuming u had all 4 flat valves, that comes out to roughly 8 tenths gained from them (with my setup). is that right at all?

or wtf am i doing wrong, cuz everyone always says they do practically nothing for compression ???

(i only have the ex, figured i might as well use them since no one is ever gonna buy the damn things from me anyway)

 

No Way....more like .2-.3 CR

They are heavier...and don't flow as well as ITR.
