Re: Headgasket Issues 3.8L
I can't believe no one has mentioned Fel-Pro yet.
I would take the heads to a trustworthy, competent machine shop and let them check them out. The only problem is that a trustworthy, competent machine shop is sometimes harder to find than an uneaten Little Debbie cake in a room full of fat people. If it's only overheated once, it's probably fine. But if you can find a decent shop, I would rather be safe than sorry.
