Interesting...I brought it off someone who had just had it built and told me it was fitted with the 29cc 'ported' head..and it had been milled for a stroker. I did pop the head off but never thought about measuring the piston because I assumed it was the 29cc....but after reading the info posted earlier in this thread I'm having second thoughts.
I've never got around to fitting it as yet so still needs to be run in....
