This pair of header gaskets is designed for GM Gen III and Gen IV LS engines. Each gasket is made of multi-layer steel (MLS), providing a durable, high-temperature-resistant seal between exhaust headers or manifolds and the cylinder heads. The pair-sold format accommodates one bank of the V8 (one header manifold), making it suitable for partial exhaust installs, repairs, or staged build-outs where only one bank is serviced at a time.

Brian Tooley Racing BTR17944-2 Features:

• Fitment: GM Gen III and Gen IV LS engines
• MLS construction for reliable, heat-resistant exhaust sealing
• Direct-fit design matching standard exhaust/header flange geometry
• Ideal for single-bank header/manifold installation or phased exhaust builds
• Sold as a pair — enough for one side of the exhaust (one head’s manifold)

Brian Tooley Racing BTR17944-2 Notes:

• Two gaskets per package — covers one bank of the V8 (one manifold/header installment)
• For a full dual-bank exhaust/header setup on a V8 engine you’ll need two packages (one per side)
• Recommended replacement whenever headers or exhaust manifolds are removed or re-installed to ensure proper sealing
