PISTON DOME cc s

[Trojan]

Hi Gents, I ve had a program which covers Compression Ratios , basically you just input Stroke/Bore/CCV/Gasket thickness etc, now one of the questions is PISTON DOME cc s ?????? any ideas as to how or whats the best way of getting the DOME ccs, thanks Gents........

use a burette or similar and measure it

Cheers for the reply Sean, but what I was trying to fathom out is, is it the same way as checking for the CCV on the head , that is tilting the engine so as the plug hole is horizontal etc.......OR is there a case of a separate check on the piston alone, cheers...........
