220 Silver Diamond vs Lycoming Engine

Does anyone know if the 220 Silver Diamond engine is similar to the 220 Lycoming engine?

I have found the torque specs for the Silver diamond, wondering if it will be of use for my Lycoming engine.

I would say no as I believe the lycoming to be a side valve engine and the silver diamond is an overhead valve set up.
