Description

Built specifically for the Vortec 4200 (LL8), this gasket is cut from 0.040" C110 copper and formed to include a crush ridge that conforms under bolt torque for a leak-free seal.

Unlike composite or multi-layer steel gaskets, this copper version handles heat cycles, boost, and vibration without blowing out — perfect for custom turbo builds, high-output N/A setups, or anyone tired of replacing gaskets after every pull.

Each gasket is CNC cut and formed in the USA, using precision dies to create a uniform raised ridge around each port. This design provides a reliable seal even with minor flange imperfections or uneven torque patterns.

Installation Notes

• Clean both mating surfaces before installation.
  

• Torque evenly and retighten after one full heat cycle.
  

⚠️ Not returnable once installed due to material deformation during crush sealing.
