Yes, really depends on all that it's gonna need but around $450 plus shipping for a basic deck and valve job.

crazy88,
A good machine shop can install new valve seats in a head. Usually this was done to allow the use of unleaded gas, so this is really nothing new.  If you bundle all the head work for one shop, you may get a break on pricing. Just a thought.
Cheers,

P.S. Life is too short, and health is too valuable, to ride on cheap parade-duty tires.

Depending how far gone they are we may be able to fix the valve seat and tip the valves to keep the shims in a usable range. If not we have new valve seats we can install.
