I just put my first piston in (not german) an found the deck height to be
1mm low. This is a 2.1 with the original crank & reman rods.
If I go ahead with using these pistons am I likely to have any problems? I
know power will be reduced with the lowered compression, anything else?
Has anyone here tried it? The manufacturer has kindly offered a refund or
exchange but says many people use them with no problems - seller says the
same.

Thanks, Tom
