are balanced to plus or minus 2.5 grams throughout the set. The valve pockets are designed to handle most
aggressive camshaft applications up to .650 lift. The performance skirt design allows the pistons to work properly under intense
heat and tremendous side loads without scuffing or splitting cylinder walls. Most normally
aspirated pistons are designed to operate at just .004 piston skirt to cylinder wall clearance.
