Need 800 8:1 piston kit

2013 800LE
Anyone know where to get a 8:1 compression ratio piston kit?
Includes: pistons, rings and pin

Stock is a 7:1 for the 87 Octane.
8:1 requires 93 octane and should add a little power.

I have to re-fresh the upper due to low compression and might as well try to improve a little.

It has a Power commander and auto tune with a modified exhaust.
