    I am using Mr Gasket copper on my Hedman Elites. These headers have 3/8 flanges. Not familiar with the super comps.

    Super Comps have a thinner flange. (1/4"?)
    I used Percy's Dead Soft aluminum gaskets on my Hedman Elites... 10 years ago.
    I haven't noticed any leaks yet!

    The thick, multi-layer design seems to compress nicely and creates a good seal.

    I also used multi layered soft aluminum and that was 3 years ago-no leaks

    Soft Aluminum for head to headers and Remflex for flange.

    Since you have Vortec heads... I would go with the 760-66121. (They specifically mention "Vortec".)

    I think I used the 760-66011 for standard old-school small block heads.
    It's been a decade... I would have to search my project thread and maybe come up with a number which won't be specific for your application.

    Hop to it, Harry!
    Iola only is two weeks away! :D
