    Percy's Seal-4-Good Reusable Flange Gaskets are multi-layered and made from a special "Dead Soft" aluminum that conforms to header flanges for the ultimate seal. Because made from multiple layers of dead soft metal, Seal-4-Good easily conforms to small imperfections that copper gaskets simply can't, and these gaskets will not blow out or burn out when properly installed.

    Rated 5 out of 5 by from Sealed up Good After buying another brand of Aluminum Gaskets that wouldn't seal up I was reluctant to buy these. I went to a set of 1/8 thick ceramic gaskets that blew out a piece in short order. I saw a set of the Percy's that my friend had and liked the construction of them better than than the other brand of Aluminum Gaskets. I bought a set of Percy's for my car and they sealed up real good.
