i blew out my old header gaskets....and i replaced em with some cheap paper ones...but a bolt wobbled loose and then i blew the paper gasket apart...soo i decided that i would try the cooper gaskets!! well i got the mr. gasket copper ones for the d-port...and i still have a leak...its quite at idle...but man i give it gas u can really hear it!! soo i let the car warm up....then shut it off soo it would cool down...then i tightened them again...still a leak??? wtf??? should i use different gaskets???

 

The only gaskets I've ever gotten to work were the Earls Aluminum/Carbon gaskets. They cost about $40 but they sealed up great, and didn't even require re-torquing.

These were the ONLY ones, I tried just about every other type/brand out there, and these were the best.

 

i have used those ones that are 4 or 5 strips of aluminum (maybe stainless steel but it hink they are aluminum) they are awesome. I don't know what brand or anything but they work great

 

Mr Gasket makes a D port composite gasket in their Ultra seal line and they have worked well for me.Get rid of the copper.

 

If you're blowing header gaskets, you might consider better bolts. As soon as a bolt loosens, no gasket is going to hold up. Standard Fel-pros will work just fine. Without turning this thread into a Breslin bolt promotion, do a search on them and you'll find plenty of info.

 

thanks guys....im going to try the earls aluminum ones!!! i have heard good things about them from other sites..thank you guys...and i will look into different bolts

 

I LOVE the felpro gaskett. I cant think of the # off hand but there awesome. There about 30 dollars but well worth it, dont change bolts just use blue locktite.
