According to Peter Kent:

Whilst I havent had the opportunity to "cc" them in situ rough benchtop
calculation indicate thet the 8.13:1 rover piston will duplicate the
9.0:1 CR of the stock P76 piston in the P76.
Whilst the compression height of the P76 piston is higher the bowl in the
top of the piston is a lot bigger than the rover one.
P.S. Jan, you stuff has at least migrated from the back of the shed to
the front, so there is hope yet :-(
