Overview:

Mr. Gasket Performance Valve Cover Gaskets are high-density cork/rubber blend gaskets that use evenly sized cork particles distributed evenly throughout the rubber binder. The result is a compressible valve cover gasket without leak paths. These gaskets create a positive seal by controlled swelling of the gasket material when exposed to hot engine oil. Provides excellent flange sealing and durability. For original equipment replacement, high performance street, drag race and oval track use.

These gaskets are .312 inch thick. That's substantially thicker than stock which can allow for additional valve train clearance.

    The best for fetching enthusiasts
    We have two lab mix dogs that love to play fetch but also have very strong jaws and sharp teeth. Tennis balls last about 10 seconds. I have used these for several years now and they are the best. They glow in the dark for night fetching, have two holes and are hollow so they whistle when you throw them. The dogs chew them like gum when not fetching and they hold up. They last about a year before starting to tear (this is with almost daily use). These balls are their favorites and get they upset if I use something else.

    My dog's favorite
    I have a 4 year old german shephard and this is her favorite ball. She often loses them and has to resort to a previous ball she used to play with, but when I line up several balls she chooses this one every time. When I tell her to search for her ball so we can go play she passes by all the other balls we have for her to look for this type. It has gotten so bad that I buy these in multiples because we play so much outside that she looses them and I almost have to order her to pick up an old ball when she can't find this one just so we can go outside. She loves to chew on this ball, I know that she could destroy it if she wanted to but she just likes to half bite on it. My dog loves this because the holes on each end make a whistle sound when you through it and she has become great at tracking it through the air via the whistle, I like it because it glows in the dark. So, in the early morning when she goes outside to the bathroom I charge the ball with a flashlight and I can watch her walk around the yard (we live out in the country and it is mostly dark all around us). Best ball for me and my dog.
