Big Block Chevy Race Billet Valve Covers with Quick Release Burndown Breathers 37-120BLK 

These beautiful Big Block Chevy Valve Covers will cure your gasket issues, look good, and offer a pre machined burndown option. 

Utilizing a standard 2 bolt burndown pattern as commonly seen on Billet Hemi engines, these allow for use in even the highest horsepower engines, pairing our quick release burn down fittings and a proven valve cover. Our quick release burndown fittings come with a variety of sizes (choose in options), as well as can be faced forward or rear thanks to the symmetrical pattern and oring seal. Included is an internal bolt in baffle for the burndown fittings if you choose. 

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.  


  • Included Quick Release Burndown adapters (choose fitting size in options 1.250" barb, 12AN or 16AN)
  • CNC machined from solid 6061 aluminum
  • Black Anodized
  • Made in the USA
  • Includes Hardware
  • Reuses Factory Style Gaskets
  • Lightened internally for overall weight savings

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: Our burndowns include an optional bolt in baffle, however, 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.*
