TFS 215 Head MELTED!!!! WTF???
I agree 100%. It had to have been extremely hot in there to do that to the head. Did you log air/fuel by chance??

I think its a combo of all of your suggestions. Next time the stand alone is getting c16! The tune will be checked out just to make sure. Also I was just about to re-tq the head bolts before this happend. But this time everything is getting re-tqed a few times just to ensure that everything is perfect!!! Thank all you guys for the info.

Well ... We have run more comp. and way more gas on the same TFS heads with no problems at all. With that amount of nitrous I don't see the need for O-Ringing either. We have run .051 Cometics 11.5:1 comp. and a 400 shot on a LS2 with ARP Bolts on the heads with no problems at all !!!

I know this is a really old thread but I just ran into the exact end result with the same parts with the difference being mine is boosted. Anybody else experience this and have a known solution? Mine is also not showing any signs of knock. I have the log of the failure and it does not show signs of being lean. (.8 to .81 lambda) I'm gonna chase to theories, reinstall, and hope for the best unless you guys know of a permanent solution.
I'm gonna look very closely at the size of the bore bevel/chamfer at the top and see if the gasket is over hanging either the bore or combustion chamber at any point. I'm gonna have my injectors checked, cleaned, then re-checked in hopes of finding a semi plugged injector for cylinder number 5 which was the failure point on mine.
What would you guys do?

Since it was never asked all those years ago when this thread was started, I have to wonder what rpm people were trying to spray at. At 5000rpm, a 200 shot is no big deal, but at 2000 rpm a sudden spike in torque of over 500lbft will burn some **** down.
