Its actually the cylinder bore that is honed and its the process of making the clinder bore as symetrical as possible plus creating the criss cross score pattern in the cylinder bore walls. A sophisticated piece of machinery will hone a block at a given operating temperature which allows tighter ring to bore clearances providing better compression and slight power increases.....in the race world.

Agree with above. Honed cylinders require new rings. The only clearances associated with this are the Piston / cylinder clearance - which should not be an issue for honing, pistons are only normaly replaced through wear or after a re-bore. and ring gap. Honing will increase the ring gap hence the requirement for new rings. If the honing is done properly and the correct rings used there will be no ring to cylinder clearance, optimal ring gap and maximum compression. Rings should initially be staggered so that gaps are not in line with each other for optimum wear and compression characteristics.G
