I miss the old Mopar heads they were developing for BBM with 4-valves per cylinder. Now it seems a guy in his shop is developing a set for the LS platform....No better way to get more flow in and out than four circles that fit into a larger circle. Its the most volume you can physically provide for....And everyone knows the crazy HP motor cycle engines develop with this tech..
