Tfs 215 Melted....wtf!!!! sooooo...... we were testing out our fully built ls6 motor with full bolt-ons and more with FORGED internals with some spray (200 shot).
We were in 3rd gear on the freeway and when the spray hit the tires spun REALLY bad, it was crazy!!!
Something didnt feel right and the car was shooting out white smoke everywhere!!! we knew it WASNT a blown motor because the motor still had a good idle.....
so when we took the motor apart we saw the the driver side head gasket had blown. the shitty thing is that the gaskets were COMETIC gaskets with ARP head bolts!!!
The motor is about 11:1 compression with 18degrees of timing and about 11.3A/F with TR-6 plugs gapped to 35.
YES we will be using ARP head studs with cometic gaskets and NGK 7's next time.
But has anybody heard anything like this.... let me know what you think....
IT DOESNT seem to be detonation because the pistons are still better then PERFECT and the block also was untouched!!!!
THANKS FOR THE INFO!!!!
ALSO provided is the video when the car was racing and pics of the head and plugs... it is a convertible trans am WS9 vs a buddies BAD *** VETTE!
the trans am spun real bad and he short shifted into 4th & 5th....

I'm suprised you didn't hurt a piston. You detonated the hell out of that bank, but the weakest link went first (4 bold head design).
You have a heavy car, which makes it even more prone to detonation.
If you want to run that much timing and that plug, you really need to switch up your fuel at a minimum (like race gas).

ok just to let everyone know this car has a direct port system with a stand alone fuel system with race gas in it.... also i cant remember exactly what the bolts were torqued to exactly but im pretty sure they were fine, we used a lot of nitrous and about 4 bottles through this set-up, block was completely untouched.....we will be using a much better plug and ARP head studs.....anybody have any suggestions on how to get all the **** outta the holes cuz blowing them out doesnt seem to get it all out, also on what they would torque the head studs to????
