86 5ks update

[Randy Rock <Randolph.A.Rock-2@tc.umn.edu>]

I have discovered what is causing the coolant warning lamp to come on in my
86 5ks fwd, 163k miles. 

It seems that the head gasket has failed, causing the coolant to get into
the cylinders.  I have confirmed this by inspecting the oil (light brown).

Since I don't have anyplace to repair this at home (and my engine repair
experience has been primarily with American makes), what would be a
*reasonable* quote from a mechanic (Mpls/St. Paul, MN) for head gasket
replacement?  And can I combine this with a timing belt replacement (seems
like I could)?  The car runs out fine otherwise, with the possible
exception of needing a new battery.
