What kind of header gaskets are good and last long? Copper seals?

I have Mr Gasket ultra seals, $18.00 from Jegs. No results yet.

 

Joseph Andres,

The Ultra Seals were higly recommend from a local machine shop. I used them and they are holding up well. They tell me they resist "burning out" better than the regular "white" header gaskets. I can not tell you if that is true or not, or if copper is better. Just that they seem to be holding up better than the standard header gaskets I had in terms of durability and seal (ticking).

No copper or paper crap!
Use flow techs dead soft headder gaskets and collector gaskets thier an aluminum/lead mix that fill all the little holes and imperfections well worth the money and thier reuseable!!!!!

 

For my 89 350 TPI I used Felpro part number 1444. Been a year and a half and 0 problems. Get the stage 8 bolts while your going this.

 

I'm also using the aluminum gaskets. I haven't had a problem with them ever since I put them in. The bolts don't even come loose anymore. But before them I went throught two sets of paper gaskets, and even had one header bolt fall out. Go with the aluminum gaskets first, it's cheaper than having to keep buying new paper ones. And then if you still have a problem with the bolts loosening get the stage 8 header bolts.

 

paper gaskets are junk. i use copper with no complaints. SCE pro-copper embossed gaskets are about 30 bucks and i havent blown one yet.
