Machining off the dome on these old style pistons is the best thing you can do to them, they are super heavy with the dome. Due to the manufacturing process, they are stronger and therefore allow reduced wall cross-sections and lower piston weight. Large coolant chambers were routed around the valves and the center-mounted spark plugs, further helping the engine run cooler. The Atlas high-tech features and innovative construction seem lost to most enthusiasts who arent normally interested in early- and mid-2000s GM SUVs and compact pickups.
