You will need to have the block honed to fit the pistons.I'm not sure why you would even ask such a question.

Honed is not the correct term. He will need to have the sleeves BORED 20 over to fit an 84.5mm over an 84mm piston. A honing will not go to 0.020 inches.

You guys are mean. It's a simple question requiring a simple answer. A little silly, but we're all here to learn.

Actually I do mean hone.My Sunnen CV616 will easily hone .020".I rarely bore a block if I'm not sleeving or need to correct an alignment issue.

a lot of shops use a honing machine to bore blocks they use different stones. It is a lot cheaper to buy one honing machine to do both than buying a boring bar and honing machine.
