| Anyone ever find a secret sauce that can be applied to header gaskets to get that 100% garaunteed seal?
I know I probably over torqued the header (because I HATE exhaust leaks) causing leaks under #3 & 5 ....but I want QUIET this go round
What cha know? | |

| I use the Percy's aluminum ones. They are like 5 or 6 pieces of thin aluminum (like foil) that compress as you tighten em up. I've had very good luck with no leaks. | |

What cha know? When you find out let me know. Never had anything that was 100% positive. Make sure to check the the header flange with a staright-edge. They will NEVER seal if the flanges are bent. | |

| Based on my use of Earls pressuremaster & the SCE coppers, I have to assume operator error See....I figured tighten those mofos so they'll never leak (it being 1/4" thk material) Gotta assume based on the location of the bolts on the centerline & the leak UNDER 2 cylinders, I OVER torqued Wont make that mistake again. BTW these were Dans Stainless Tri Y's so......yah....I'll be checking surface flatness & RE-surfacing if required this time | |

| I've had good luck with the Mr Gasket Ultra Seal ones, too.
Stay away from the copper gaskets, I've never been able to get those to work!
And those Percy's ones I mentioned... I've reused them a couple times and they still didn't leak. | |
