I'm planning on starting my head job tomorrow.

I did a compression test tonight to get an idea of where I'm at in terms of
engine wear.  As the cylinders are physically laid out in front of you when
you're standing behind the engine, I have:
150 150
170 170

give or take a few psi.  This is an '83 1.9l engine with a little under
100,000 miles.  I seem to get pretty good mileage (19mpg combination around
town, light highway.)

Is this front back difference a bit weird?  I was wondering if the list
might have some opinions one specific things I should be looking for with
these numbers when I pull the heads.  (The heads are just coming off because
of a slow gasket leak).

Thanks very much for any advice,
Wes
