W2 Heads
Now this part I am not sure of its purpose. It's a spacer/bolt package P4007712. I know one is used on each head where the head bolt boss is low over the intake runners. I always read you need these for ported W2s. I am guessing they help distribute the head bolt clamp force over the ported intake runners since that area is thinned from porting. Anyone know if this is correct?
