Overtorqued Head Bolts

[Eric M]

I woke up at 2am this morning and realized that I had made this ridiculous mistake when working on my 03 5.4 yesterday. For the second and third stages of torqueing, I torqued 180 degrees per turn instead of 90. Can't believe I did that.

But, what's done is done. I'm going to pull the head, and just redo it with a new gasket. Should I be concerned about the integrity of the bolts from having been overtorqued? Anything else I should consider?

Thanks.

Me personally I'd get new bolts.

You are a beast ! But yes, get new head bolts. They are a one time use only. Was the motor already reassembled ?

Thanks to both of you for sharing your thoughts. I will get new bolts.
Thankfully, this was the first of the two heads that went in and I hadn't assembled any other parts.

I'll also lay a straight edge across the deck to see if I warped my beautiful newly resurfaced head, argh.
