Replaced my paper/metal header gaskets (that came with my Hooker headers), in favor of Mr. Gasket (copper gaskets) to solve an exhaust leak I've been having. Well took her for a spin afterwards and all-be-damned if the leak didn't sound worse. My car sounds awful. The leak is killing me and my slp LM sounds like ****...way to much crackling when decelerating. Any other header gasket you guys could recommend to help me out. Thx in advance.

Ive never had problems w/ felpro gasket but never tried their exhaust one.

That actually might mean your leak is elsewhere. If you had a leak at the header gasket and somewhere else, when you fixed the leak at the headers then the other leak would be getting more flow. I say this because I've never heard of anyone disliking they're copper gaskets.

just out of curiosity, did you retorque the bolts after the heat cycle? my friend didnt listen to me about the bolts spinning out since the gasket will compress and expand and fried them. never tried copper so im not sure if this is as big a deal but worth a shot.

Just installed some Hooker LT's and used the Felpro header gaskets, they sealed really nice no leaks at all. Used some copper gaskets between the collecter and y pipe, and thats a different story, pain in the butt

the mr gasket copper seals are teh suck, their ultraseals are what i ended up going with after the copperseals blew out

How do you blow copper out? I am satisfied with mine.

its because of the ridges that the copperseals have around the ports, if they dont line up perfectly then they will allow some major leaks, 4 out of the 8 primaries had a serious leak

I used stage 8 locking header bolts just for that reason.

I used carbon fiber header gaskets from percy's and stage 8 locking bolts, afger dealing with papaer gaskets and what not, havent had a problem yet

That's odd, never had such problems with mine.

I believe you problem is which way you put the gasket in.

Ok, Mr. Gasket says put the raised side toward the header, i did this and WOW LEAK CITY. I swapped it around so the raised side was toward the head just for the hell of it, and wow, it works, imagine that.

Which way did you put the raised side?

I too put the gaskets on per Mr. Gasket directions. Funny...how you installing them incorrectly worked out in your favor. I guess I'll try your suggestion. Thx.

i tried to use copper gaskets when i first did my headers....had nothing but leaks. tried mr gasket ultra seals....still blew out....now im on percy's dead soft alum. gaskets and have been fine ever since....bet gasket out there! hands down

Ultra seals are supposed to be pretty good, I've used Felpro 1406's with great success.

I tried the percy's aluminum. It was great until my #5 plug went, burnt and cracked the gasket, so not quite forever like the box implies, but yes probably a crazy lifespan if not subjected to such things. I'm running the fel-pros that came with their head gasket set.
Got to love those header leaks, annoying moped ticking sound you have to deal with, I went and bought a combo wrench from craftsman that had one end 3/8 and the other 7/16, and its really thin and long, I don't mind header gaskets anymore.

Sometimes if you keep blowing gaskets your header isn't flush with the head...i.e. Pacesetter.
