an acquaintance of mine, was assembling a gen2 Hemi. He was trying to do it fast and not really thinking about what he was doing. The pistons are extensively domed with huge valve notches, and the valves are not arranged in a line like a usual Mopar wedge. He managed to put several pistons in backwards, just bolted on the heads and when he tried to throw the rocker assemblies on he bent some brand new valves. You really need to pay attention to details when building an engine, especially expensive, high performance ones.
