Dittos to all the messages above. The ring land area will generally be somewhat smaller diameter than the skirt area. Also, the piston manufacturers instructions as to WHERE to measure the skirt must be followed exactly. .020" is way too much, if this is what it turns out to be. Many aftermarket replacement pistons do have the clearance built in, but I am not sure about JE. Anyway, the machinist should have measured each piston individually and bored each cylinder accordingly. Used to be that you would find several thousanths difference between the diameters in a set of forged pistons, however newer pistons and good performance brands such as JE are usually right on the money.
