Since we already had the pistons out of the block for cleaning, it was easy to run a Dremel tool with a cylindrical-end cutter bit along the edge of each intake relief to lay back the rear of the notch slightly. We removed a minor amount of material to allow the valves to travel into the pockets without hitting the edge of each relief. Most aftermarket performance pistons are designed with notches large enough to accommodate the big valve heads, so this could have been avoided had we opted to bore the block and replace the pistons from the start.
