Hello,
i have ALTIMA 2006 SE-R VQ35DE
i buy C8 cam A3505-N00C8 with spring
http://www.importpartspro.com/a3505n00c8g35.html
and Ferrea Valves 6000 Series Nissan 350Z VQ35 VQ35DE +1mm
and Cosworth 20000900 High Performance Head Gaskets .6mm

i wanna do head work
my question what the maximum HEAD SKIM?
i wanna go high compression from head
i hope u can help me

 

i don't think that nissan has a spec of what is allowable--after a quick glance all i saw was a max spec of warpage in which they consider the head to be junk.

most of the time on newer cars there is a zero tolerance on head shaving. if there is warpage the accepted method(in the aftermarket) is to heat the head and straighten it

i personally would not shave the VQ head at all considering the fitment of the timing covers/upper oil pan.

 

None. The timing chain would be off if you shaved it any realistic amount. Get new pistons.
