    Ok, I have emmisions coming up so I actually HAVE to get this done...

    Just a simple question: Do you use high temp RTV along with the metal gaskets? And if you don't use RTV how do you keep the gaskets in place while you're putting the maifold back on?

    Thanks.

    I used RTV when I installed mine. I used the RTV high temp ultra copper. Its more oil resistant.

    X2.... I don't use any gaskets at all, just tighten the manifold right to the head.

    Most of those manifold gaskets don't have traditional bolt hole in them. They have hook shaped bolt holes that are open on the bottom so you can get all the bolts started without gaskets, then slide the individual gaskets between the head and manifold...then tighten the bolts.

    I never use them either!.....

    I just put them on without any,just like GM did factory!,,every time I used a gasket,even with RTV red hi-temp silicone,they would eventually blow out and leak..

    I have the manifold shaved flat on a surface grinder if its warped at all at a machine shop(they charge about 15 bucks to do it locally)..I havent had any troubles putting them on "metal to metal"...I think headers need gaskets,but not stock cast iron manifolds..and on headers I'd use the solid copper or aluminum ones(I prefer copper--expensive,but they last,and can be re-used)... :crazy:
