Shawn,

Before you decide you might give Ken or even Don a call. They offer thread repair inserts in their catalog and I cannot imagine they'd offer anything that wasn't top shelf, thoroughly tested and endorsed by them.

While you're on the phone, ask about the potential for coolant leaks like Joe mentioned. This can't be foreign to them. For example, Chevy small block head bolts also thread into the water jacket and it's normal practice to seal the threads with Permatex before installation.
