I considered all studs because I like the idea of not having any thread
wear on the heads, but I thought that this is not possible on the 1.9
engine; there are some old list emails from bob donalds saying that the
waterpump can prevent removing the pipes when studs are used on the #2
port.  Has this not been your experience?

(I actually am thinking that even if I wanted to keep the studs, I'd prefer
to have stainless studs in which case I'd be removing these studs anyways.)
