Doesn't the 3.9L use hemispherical or semi hemispherical heads? Course it may be just canted valving for those who have a problem with "semi hemi" being used as a term relating to canted valving.
I thought I heard something about that, if that's true the performance potential of the engine should be very impressive.
Anybody else heard that, or are neurons in my brain arcing across each other?
