my 99 deville needs headgaskets. i was talking to my friend who works in a garage and he said that sometimes the heads get warped from the heat and that they would have to be replaced. when i noticed the problem that my car was overheating i believe that the temp got up to around 260.
What are the chances of my heads needing to be replaced???
Any info would be great.
Slim. The Northstar was designed to run 50 miles with no coolant at 260 degrees with no damage. Your heads are most likely fine. Just be sure to rethread the bolt holes with Jakes studs, Norms inserts or Timeserts, in that order.

Slim to none. I have never found a head out of spec yet. And we're talking 80+ engines. I know that I found a few with very minor indents from the fire ring on the cylinder head gaskets, but they still sealed nicely.

No sweat- anytime you're ready. The studs have been used on well over 100 engines (mine & stud kit customers combined) with only one known failure, and that was caused by a warped cylinder deck that was out 0.006". I believe that engine was in Tenessee. Always check the block and heads as a safe measure, just in case.
