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.

Fits Chevrolet 396,402,427,454,502 Gen IV, Gen V and Gen VI Big Block.

    My dog loves glowing fetch at night!
    Style: Glow Balls (Pack of 3), Size: 2.5 inch
    Fantastic. Sturdy. My dog loves them Glow in the dark is great for fetch at night. I keep a flashlight with me because the glow doesn't last really long. But they charge very quickly and are really bright.

    Indestructible
    Style: Fetch Balls (Pack of 2), Size: 3 inch
    These balls are indestructible! We have a lab and a lab mix and they CANNOT damage these balls. They love them for fetch and to just chew on them (slightly squishy, but NO damage). Best toys we have bought for them.

    Great trial set. Just be careful throwing the orange one!
    Style: Assorted Balls (Pack of 3), Size: 2.5 inch
    Blue isn't that easy to see in the yard White charges with bright light/UV and is truly a game changer for night-time fetch. Both dogs clearly favor it. Orange is easy to see in the grass at day They're 3 different weights as well, so double trial. I prefer medium for my big dogs, though light performs well too The orange is HEAVY and unyielding. Do NOT throw it with a ball thrower. It could damage your house or knock your dog out. Seems tough though.

    Best Balls Ever!!!
    Size: Medium
    These are the best balls ever! We have 2 very active ball loving dogs and these bounce very well and they actually hold up with active play and chewing. They still look brand new after daily use for months!
