    121 - Mr. Gasket Intake Manifold Gasket Sets is rated 5.0 out of 5 by 3.
    Rated 5 out of 5 by from Great gaskets Excellent gaskets for my Rat Motor. Thickness was good for new head/uncut manifold application. Also better for use with aluminum intakes rather than the harder FelPro gaskets. Because of lower torque on the intake, they seem to seal better.
    Date published: 2019-07-11
    Rated 5 out of 5 by from Great Gaskets I’ve used these for 15+ years. Good fit on Edlebrock 454R intake. Worked on BBC 990, as well as Dart Pro 1 heads. Never had a leak.
