found this while i was researching what heads I want. look under "crankshaft" section. specifically "The forged crankshaft of the RL is similar to that of the MDX, but with revised counterweights to accommodate the weight of higher compression pistons."

will this effect the build at all? considering im using RL pistons with an MDX crank that hasnt been "revised".
