On the basis of the manual's recommendation I have decided not to mill the
head from Susan's car (B21F with 0.012" bow front to back). Rationale is that
the manual says up to 0.020" doesn't need to be milled, also the gasket is
quite a bit thicker than that, and where it blew before is in one of the
areas that will be tighter due to the bow. As a longtime professional
metallurgist and failure analyst I am pretty familiar with ductility and creep
characteristics of aluminum castings and feel that this is a good recommendation.

I have hit a minor stump, though. I failed to remove the gear/pulley on the
front end of the cam before I took off the timing belt and am having some
trouble getting it off now. I've borrowed a strap wrench that fits around the
gear and seems to hold it fairly well (although I wish I had an old timing belt)
and tried with an 11/16" box wrench, the smallest I had that would fit on it,
and knocked the corners off the bolt. I plan to stop at Sears to buy yet
ANOTHER %#@@ metric socket (16mm). Before I start applying greater amounts of
force, I would like to confirm that the single bolt that holds the pulley/gear
on is indeed a right-hand thread.
