- Engineered for engines without smog equipment or fuel-injection heads, making them ideally suited for traditional carbureted Big Block configurations.

- Shorty header design delivers maximum ground clearance, streamlined installation, and improved engine bay access.
- Not recommended for use with aluminum cylinder heads.
- Not legal for sale or use in California on emission-controlled motor vehicles.
- Due to the aluminum cylinder heads on Generation 6 engines, 502 BB Chevy applications may experience clearance issues. The underside of the header flanges may contact the head bolts, and machining may therefore be required.
