hi guys,
i did a header swap on my 97 z,but had problems,and needed my car back,so i put my, stock manifolds back on,anyhow,i used brand new copper gaskets,and locking header bolts,and i have a exhaust leak on the driver's side,the gasket is facing the right way,should i have sprayed the gasket with something?or should i just buy the dead soft aluminum gaskets?,im really looking into the pacesetter long tubes,so i would be able to switch them then,but basically you think the copper gaskets just suck,or do i need something to spray on them first?thanks alot.

ttt,anyone have any input???thanks

 

Use GM OEM gaskets.

 

I never used the copper ones, I'm not sure how well they hold up. Most ppl use the felpro 1406's i believe, I use them on my setup and they have been trouble free for over a year of use. They are one time use though, but I'd recomend you use the felpro's.

I used the Summit brand Dead Soft Copper Header Gaskets with no problems at all, perfect seal. In fact I think they are better in the fact that they have a "crush seal" and they conform to unflat surfaces better than fiber gaskets.

 

I used Copperseals on my 94 with hooker LTs and have not had a problem so far.
I don,t know if I would have used them with the stock manifolds.
The felpros would probably be better for that.

 

hi,
thank's guys for the reply's, i usually always use the percy's dead soft aluminum gaskets,but at the time summit didnt carry them,and a few weeks later i saw them in the jegs book,so that's why i bought the copper,but anyways,i will try the percy's this time coming up,and thanks for your input.
