There's been a lot of talk over on VWVortex about this - everybody's
jumping on the 1.8 head bandwagon, claiming it's worth 10hp or some
rubbish.  People who have driven the two back-to-back claim the 1.8 is
faster.  If you're sticking with a stock head, then get the 1.8.  If you're
porting it, and you really should, then it's irrelevant, since you can port
a 2.0 head to match a ported 1.8 head.

That's a big bonus with the Supersprint header - it comes with a small
resonator that sits after the collector and flex joint, right where the cat
should be.  Passes visual inspection every time :)

As far as valves go, if you plan on machining them in any way as part of a
port job, why not just spend the $100 or whatever and get new ones?
