[Question for all those with a 16v 2.0 block and 16v 1.8 head]

[dwitt1@satx.rr.com (dale witt)]

Dave, are you sure that the 2.0 head has better air flow than the 1.8?  I
found the opposite to be true.  Tuners and shade tree mechanics seem to feel
that the 1.8 (p/p) on top of the 2.0 bottom is the way to go....maybe I have
been talking to the wrong peeps for a long time??  I have used the 1.8 on my
2.0 and 2.1.
