The 1.8 G60 head is pretty inefficient and flows poorly, air is drawn in and expelled on the same side of the head. The 2.0 OBD1 ABA head is an X-flow head and flows alot better than the 1.8 G60 head. That will be one of the later swaps though as Im not too concerned with undertaking any other major projects at this time. Just getting the car up and running flawlessly.
