By the time you guys dick around saving old pistons, replacing and finishing to size liners, ordering special rings of unknown quality etc. you'll be money and time behind simply overboring the block and fitting oversize pistons.

Was it a FSM for a 617.952 engine ?
Have you checked to see how much turbo annular oil cooling ring pistons cost ?
Yes , there is a proscription against over boring the block.
First as hinted above concerning the cost of oversized ( or even stock ) pistons...
Second, this is a sleeved engine. It is made to have the sleeve pulled out and new sleeve pressed in... then you take each piston you have and measure it...and then bore and hone that hole to the correct size for the piston going into it. Look at the price of the sleeves.. CHEAP compared to proper machine work ... ( aside from the fact that the FSM says to replace them ) .
You sound like you are lacking in the kind of attention to detail which is required to rebuild these engines and get satisfactory life from them afterward...
We study the FSM and have them at our elbows when working on these engines... as compared to dashing off advice from ' looking' at ' A ' FSM long ago...
At the very least you are taking a chance on misleading some newbie in a serious and costly manner...
