the mp stage 6's have some interesting design compromises. the valves are too short, the valve spring pockets are too deep, and there were some qc issues early on. the short valves and deep spring pockets restrict the port shape going into the bowl (the roof of the port is low and can't be raised). there are plenty of eddies running nines, maybe even eights, prolly.
