Combustion chamber design and ports. The E7 (HO) heads don't have shrouded valves like the E6's. The E6 has a heart shaped combustion chamber, which shrouds the valves.(supposedly creates a swirl effect for better combustion) I think the port size is a bit smaller also on the E6's.Builder/Owner of Badass Panther Wagons
