The number stamped on the piston, in this case 67-554, is the number for the bare piston. The numbers in the parts books usually is for the complete piston assembly which makes it difficult to identify pistons unless you have detailed information on the numbers which I do not.

Whatever the case I hope these pistons work out well for you RR, good luck.

I would say most definitely higher than 10:1.
I had a set of 10:1 many years ago and they weren't anywhere as high as that.

Once I've got them fitted and had a run I'll provide some feedback via my road racing sidecar thread, but don't hold your breath this wont be before March.
There aren't that many practical uses of 14:1 pistons on a typical A10, so lucky for me Bender only lives on the track. He would be lost without his alcohol  *beer*
