hey i was just wonderin if i was building a stronger i6 would it be worth using the AU VCT bottom end with and EL XR6 head for avalibility with cams??

Or is the stock ef/el bottom end just as good.

Also wats the deal with these XF throttle bodies do they make a difference on EF/EL non XR6 motors.

Cheers

AU vct bottom end is exactly the same as any other bottom end,
