Vortec Heads 062 or 906 Question
I have read somewhere in this forum about the difference in the vortec heads for the L31 motor 96-98. Which head is the one that kills low end torque and flow? I think I remember reading that the "906" casting #'s were the ones to be avoided. Need any advice or info.
thanks
