Common problem with budget pistons. |

When you buy cast pistons the typical result is the pistons are way down in the hole. The piston companies do this because their big customers, the wholesale rebuilder shops have less machine work to do if every piston is below deck even on blocks that have been decked repeatedly. The loss in compression also helps the engine last until the 90 day warranty period is over. If the pistons were designed to be zero deck on an unmachined block there would be extra labor involved to cut all the pistons down on decked blocks.
Yet another reason why it's better to buy quality pistons from Ross, JE, Wiseco, Aries, Venolia, Probe etc. You get what you pay for.
