Volume of the domes on Pistons - have I got it wrong?

[Kevin.payne.15]

Guys. On my last thread with the assistance of many others I've correctly identified the engine as a mk 2 2000 with domed Pistons. Thanks

 

I've very accurately ( I hope) measured everything as suggested with the oil and plate 3 times to get consistent measurements and derived a dome volume of 7.5 cc where as the link as provided by Clive says it should be 8.66 cc. Humph

 

Ok so not a massive difference but it does make a difference to the planned head skim values. Does anyone have an alternative value? Were they different on the 2000 to gt6's?

 

At a bit of a loss now! Makes a mockery of the accuracy if I just use this different number

 

Thanks
