I have the Wiseco 444 piston, works just fine. However, you need to send your piston and cylinder to Millennium Technologies to have it bored and plated to match the piston. Something on the order of $250 for the machine work, but fast turnaround and great shipping rates.

The Luke's kit comes with a prepared cylinder in exchange for yours.
