I just want a reliable ride, I broke a ring in #4 and cratched the cylinder but the machine shop said it should come out ever for stanard bore, but I can't seem to find stanard pistons and rings. So, I'm leaning toward the 59, all new seals and gaskets, might have to go with new value guides and seals too, but not sure yet.
If you have scratched the cylinder wall, more material will have to be removed to make it smooth again. This is akin to high mileage wear. Although, you may still meet service limits, the engine won't last as long because the tolerances are now much closer to wear limits due to the honing.
Can your machinist tell you what std piston to cyl wall tolerance will be?
I'd probably go with the 59s for maxium longevity. Bore your existing sleeves for these to fit properly. PJs clearances are just fine. Were I you, I would have the new pistons on hand to measure before having your cylinders bored and honed. With luck, they will all be exactly the same diameter. Your machinist can then bore and hone to you specifications. Don't forget to end gap the rings.
Even if you don't replace the valve guides, do replace the guide seals. It will cost you another gasket set to replace them later. Unless, of course, blue exhaust smoke somehow appeals to you.
Reassemble, break in, and ride!
Cheers,
