Just a thought why not sleeve cylinders back to earlier spec??? Going 20 over will it compromise reliability and is rest of engine, drive train, and is it capable of handling additional power?????????

I can not answer that but with Jacks info and researching out a renowned engine builder in your area you should be able to get it taken care of......

IMO it would be cheaper and faster to buy new cylinders and pistons, there is a lot of machine work to resleeve and then to find out they may or may not fit the cases? Plus you can rebore at even sizes again from there JMO

You don't need to re-sleeve the 4.060" cylinders; they will easily accommodate a .020" over bore; I have run them a .030" overbore and would not be concerned with a larger over bore.
CP, JE, Wiseco, MTC and KB are piston supply options. They might not be "off the shelf" and you will pay a premium; I know for sure CP can provide them as I have bought custom piston sets from them before. The problem with CP is that you cannot buy just one set; you need to buy 2, IIRC. Call Randy at King of Cubes. He can include your piston set in one of his orders and save you some money. Your biggest problem will be making sure that you find a piston/ring/pin assembly that is close to the same weight as the H-D piston. Heavier would be OK but is lighter, you will most likely have an irritating harmonic vibration somewhere in the rpm range. Or, you can select any piston you want and have the crank balanced to that piston.
MTC can resleeve your cylinders for $370; I have run a set of their resleeved cylinders and can recommend them for quality and workmanship. If you decide to go that route, send them a set of OEM pistons and they will bore/hone to fit.
