You need to send in the head to the shop for pressure testing, milling, etc. While it will cost you a bit it is worth the money

It's only a necessity if it's a MHG... Having the head cleaned up and pressure tested is always a good idea, regardless of what gasket is used. Fortunately, most shops won't charge a large sum of money for the service

Of course it'd be smart to have it checked and made sure theirs no warpage. But unless he is using a mhg theirs no need to have it resurfaced unless he wants too..

If the Joker that replaced the head gasket before me, it would of saved us a lot of bother. After a lot of work the dealer found the crack in the head. It is close to the valve cover and was hard to spot. A simple pressure check would of spotted it.
