hone

Ive used a stone hone for my banshee cylinders and the blaster and I have not had any problems catching a port.
 
It's butt easy. You mount the hone in a drill and work it up and down the cylinder. Experience will give you the perfect 45 degree cross hatch marks.
 
They are the criss cross marks that retain the oil the keep your rings from wearing out immediately.
