Upgrade your 1973-1987 Chevy/GMC Square Body truck with these polished stainless steel long tube headers. Designed for Small Block Chevy (SBC) engines, these headers improve exhaust flow, increase horsepower, and enhance performance while providing a durable, corrosion-resistant finish.
🚨 IMPORTANT INSTALL NOTES – READ BEFORE PURCHASING 🚨
✔ Header Spark Plugs & Heat Shields REQUIRED for Proper Fitment
To ensure proper clearance, you MUST use "Header Spark Plugs" and plug wire heat shields. Standard spark plugs WILL have clearance issues.
Recommended Spark Plugs:
Accel 0576S (Taper Seat)
Accel 0414S (Gasket Seat)
Plug wire heat shields are also strongly recommended to prevent heat damage.
⚠ Failure to use the correct spark plugs may result in fitment issues and difficulty during installation.
✔ Fitment for 2WD & Lifted 4WD Trucks
These headers fit 2WD and lifted 4WD models.
🚨 NOT RECOMMENDED FOR STOCK-HEIGHT 4X4 TRUCKS – You may experience front driveshaft clearance issues on stock-height 4x4 models.
Lifted 4x4 trucks will NOT have clearance issues.
