Side relief into the forging instead of machining all that material off makes for a stronger and lighter piston
DLC wrist pin for added protection against friction and wear
Internal and external bracing and internal milling reduce weight while maintaining strength qualities
Broaches wrist pin grooves machined in the pin bore to help increase oiling of the wrist pin.

Generally speaking, JE Pistons are designed and tested to fit OEM cylinder heads. So, there's no guarantee that these will fit with oversized valves. A good indicator is whether or not the stock piston will work with those valves - if the valves you've installed require machining of larger valve pockets to fit, then you'll need to do the same thing to this, or any other piston we sell to fit your machine.
