Tu3S Head Skim Amount

[N3VRAM 12 1 Cars]

Hi All,

 

Was just wondering if anyone knew what the maximum 'safe' amount would be to take off the head?

 

Thanks

It all depends on what piston's you're using really, regarding any valve-piston or intruder-chamber contact problems, because the casting can take well over a mm off.
