After we receive your cylinders we will inspect them and determine what oversize pistons it will take to make the cylinders straight. We bore your cylinders on a boring bar, final sized with a rigid hone.  The ports are chamfered in a 3 stage process to ease the rings back in, including a final hone to extend engine life, and improves performance.
