    Rated 1 out of 5 by from Steel core valve cover gaskets The quality and manufacturing of the gaskets was very good. Unfortunately the valve cover bolt holes did not line up. I was using valve cover studs and I had to stretch the gasket to slide over the studs. Due to the steel core, the gaskets became distorted and did not seal. This rendered them useless.
    Date published: 2015-09-10
    Rated 5 out of 5 by from Fit perfectly and no leaks.... I installed these gaskets when I replaced the heads on my 1985 GMC Seirra Heavy Half Ton 4x4 and have not seen one drip yet. They have worked better than the cork gaskets that came with the truck from the factory. Great gaskets.
    Date published: 2015-03-07
    Rated 5 out of 5 by from My new favourite As good or Better at a lower cost. Fit perfectly and no issues so far. I'll definitely buy other jegs products in the future.
    Date published: 2015-02-14
    Rated 5 out of 5 by from Last VC gasket you'll ever buy This is the latest and best in a generation of valve cover gaskets. You'll never have to buy another pair for this engine.
