The pistons would have to be solid ceramic for that to apply.
Any good machinist has a little book where he writes the numbers down..at least i did. You never hone until you get the pistons and measure all of them. Some machinists are lazy and only measure 1 and go to town. Some manufacturers tend to have pistons with crushed skirts, which could cause your problem. Also, sometimes you run into some pistons that dont have the correct cam slope machined in them (piston skirts arent round). Ross pistons tended to really suck. Plus they're heavy as rocks. JE's were usually really good, as well as TRW's. I didnt do enough Wiseco's to remember. Anyway, you measure all the pistons, about 3/4" inch from the end of the skirt, and then rotate in the same spot a bit and measure, and then rotate the other direction and measure...to check the cam slope). You write the number down, and do your final hone based on that number. You should never bore and hone say, .030 over, and then shove some .030 over pistons in them. the hone is always based on the diameter of the largest piston skirt, after it has been crushed. (meaning after the skirts collapse a bit which they are designed to do. Thats why you dont measure at the very end of the skirt). After you've honed the block, you write down that final bore number, down to the 4th decimal (10 thousanths), next to the piston measurement. If you have to pistons that vary by .0015 to .002, then you shouldnt run them. If the machinist is willing, have them give you the piston diameter numbers and the final hone numbers. If youve already told them the engine is bad, they will either give you BS numbers, or wont give you any at all. Either cause they're ass holes, or cause they didnt measure them in the first place. Another thing about ****ty machinists, is that they dont periodically check and adjust their micrometers and bore gauges. You may either have short skirts in relation to the piston pin bore which is causing them to rock, or the wall clearance is too high on 1 or more cylinders, or you had a bad batch of pistons, where some jackass (manufacturer or machinist) dropped a piston on the floor and crushed a skirt. Crushed skirts were usually crushed by about .005-,010". Sometimes more depending on the severity. Its either one of these, or not even related to pistons. Maybe you have too much pin bore clearance, or main or rod journals that are too small for the bearings (1 main or 1 rod would be a knock...all of them would sound like a diesel), or maybe valvetrain noise.
