combustion chamber volume

[Trojan]

Apologies if this has been covered just looking for advice, basically, a 225 AFR 9.5;1 Cylinder head for a Rapido Race, checked with a burette and it showed 22cc and I ve removed the Head gasket giving me a Squish 1.20 whilst leaving the base gasket on.......All this is showing the 22cc, what I would like to know is , I have been advised that it should be 27cc, can anyone confirm this.....thanks chaps

to find the required combustion chamber volume use the formula CCV=CV/CR-1, CCV=combustion chamber volume, CV =cylinder volume, CR= compression ratio.
For yoursCCV=225/9.5-1, CCV=225/8.5, CCV= 26.47cc. Hope this helps
