Gasket is less then $100, tools required = less then $100 so I'm going to say about $150 or so.....


Want a shop to do it? expect to pay $75+ an hour for labor and $100 in parts....It's really not as hard as it seems, just time consuming...
All you need is a good tq wrench, some metric sockets (12pt sockets for the head studs) and some patients.
