Big Block Chevy Billet Valve Covers by Motion Raceworks 37-110BLK

All of the features and benefits of our LS valve covers, but for the Big Block Chevy platform. These valve covers were designed to refine and offer solutions for the BBC crowd.  

Featuring internal baffling, these valve covers are a suitable and great replacement for a street driven vehicle utilizing these baffles to keep the oil IN the engine and to get the air (PCV) out.  When racing or for large horsepower engines, you can simply remove the baffles for maximum venting.

These billet valve covers come with new hardware but utilize a factory or aftermarket style gasket. While we originally wished to integrate an O-ring seal, we learned that the valve cover rails varied and we did not want to sacrifice sealing capability.  


  • 16 ORB Breather Ports (Choose 12AN or 16AN fittings)
  • Internally baffled to keep oil in and get pressure out
  • Black Anodized
  • Made in the USA
  • Includes Hardware
  • Oring Seal Oil Fill Cap

These covers clear some shaft style rocker arms, but please refer to the dimensional drawing to make sure it will work on your setup.

*Note: We do not suggest leaving baffles in for any setup that runs on Methanol or is a high horsepower combination.  If you would normally run to a burn down tank, please do not use baffles.*
