    Rated 5 out of 5 by from Fits 96 Impala SS LT1 Like a Glove Had copper header gaskets that leaked. Replaced plugs and wires at the same time. These gaskets are highly recommended on the ssforums and after installation I could see why. Great fit and I have not experienced the bolt loosening that I am used to with other header gaskets. All that and replaceable inserts make this a no-brainer. Highly recommended.

    Will these gaskets fit the ZZ6 Crate Motor? I would like to use them with a set of Doug's Headers (D308) if possible.

    Asked by: B Eazy
    Yes, these will fit with your Dougs headers in a ZZ6
