They are worn out, rusted through, front ends blown out aluminized Magnaflows that I've had on the car for 7 years. I'm replacing them tomorrow with new stainless steel magnaflows with turndowns. No more tails for a while.

Hum magnaflows with what mid-pipe?? shorty headers?? cats?? your car is bad ass, i cant wait to put in my 331...my car never sounded like that with magnaflows...but then again it didn't have a 331 behind it, just wondering if i should stick with my bassani's now... any trades out there for some stainless magnaflows???

:notnice: That's not good. Have you pulled the heads back off the engine yet? Mine was leaking in the middle. Not sure what that stuff is they space the metal gaskets with, but it failed miserably on both of mine. :bang: My engine builder said Cometic knew EXACTLY what he was talking about when he called in. He told me, they even said they were working on a fix for the problem, telling us it's fairly common. Sounds like the person you talked either didn't know anything, or I was lied to. :roll:

So far the replacements are holding, but my builder coated the hell out of them. Feel free to point Cometic to this thread. I'll talk to them to back you up. Hell, even have a video of the leak. Watch the end of this: http://www.100mphclub.com/movies/331_idle.mov

Good Luck and keep us all updated. Who knows if mine will start leaking again. :mad:
 
yea they said it was a problem they expereanced alot.... they told me to use that copper spray "next" time.. and i was kinda pissed because they shoulda sealed the "first" time...
i think im just gonna go with a graphite headgasket this time around caues i dont want to rely on copper spray when 15lbs of boost hits
 
off the top of my head i think its just a .040 gasket.. but it could be thicker
i dont have to worry about compression a whole lot with my slightly under 9 to 1 compression...
id like to talk to ur builder to see exactly what he did to the gaskets... i might try to reuse them
 
talked to doug about it and he gave me step by step on how to prep the headgaskets and re-install them and he's talked me into giving the cometics another try...

he's one hell of a nice guy
