Yes, the compression height is shorter. If I can find the dimensions on the Griso rod I could compare to my V11 Sport rod. The compression ratio would be way off if I installed them as is in the V11 engine. Maybe the crank is different?

Thanks. I compared the pistons and the Griso piston and its is 6mm shorter than my V11 Sort piston. The rod length must be different since the cylinder deck height is the same. Not sure where to source a pair of rods. Bore and stroke is stated as 92/80mm on both engines.

Does anyone know if a piston/cylinder set from a V1100 Griso 2 valve engine will work in V11 Sport engine?
