I think its that this head gasket shouldnt be run at 600whp But anyways, here is a pic of the headgasket. How does she look??

 

IP runs the 3mm HG at well over 700 whp with no problems as do I. Its the tune and possibly the install, not the HG. Me, fernando, IP and many others that know their sh*t all agree on this.

 

I dont think they were tq'd to 90 ft lbs. It seemed fairly easy to loosen them today. Maybe I'm just that strong lol. But some probably has to do with a little aggressive timing. On the dyno it was fine but on the streets was a whole different story

 

How does this look rather than my last one??

 

Damn you didn't waste any time ripping it apart like JoeyBalls did

Looks like you found your problem, would have been interesting if you tried to tighten the studs with your torque wrench at 90ft/lbs before you removed it to see how loose they actually were...

 

there was a rather large thread a while ago were i actually took the time to call and get specs based on psi strength, stud diameter, etc, and came to the 100% clear consensus that per ARP's instructions, the torque of our ARP 195,000 studs is 80ftlbs.

search and dig it up if you dont believe me. Spoolin was in there, he knows.

 

Looks

 

 

It's not supposed to be torqued to 90 ft lbs with the molylube, its supposed to be torqued to 80 ft lbs per ARP. I just did a buddies head with ARP headstuds and confirmed the torque on the sheet they sent with the studs.

 

Here's an off the wall question: did your tuner datalog any of the dyno pulls you can pull up to see the knock count and/or voltage during the pulls?
