Stock headers won't seal

[NoviBlown]

I understand that but in this case I'm using the factory Porsche headers and not aftermarket. I would hope that Porsche built them well enough to not warp after 22,000 miles. This car was previously owned by a 65 year old woman who took meticulous care of it. It has all the receipts from Porsche and all the regular maintenance was performed. I also notice the CV boots and the clutch was replaced at only 10,000 miles. I hope this isn't a sign of how unreliable this car is going to be.
