There are sizable cutouts in the piston to allow for clearance. Below are the pistons in question. The raised center section bumps the compression from 9.4:1 to 9.8:1.
These are the 9.4:1 pistons:

Are you saying that because of the higher strength/unlikeliness of failure from the chain, that the manufacturer can increase CR without worrying about an increase likelihood in breakage?

Also, if one were to open up the engine, break it down all the way to the pistons and find the indents in the piston head for the valves, is that a 100% no doubt about it non-interference engine?

Lets ask the expert.
