Enginetech GM207HS-D Engine Cylinder Head Gasket Set GM 3.4L 207 OHV V6

The Enginetech GM207HS-D is a complete cylinder head gasket set designed for General Motors 3.4L (207 CID) OHV V6 engines. Enginetech is a trusted name in engine rebuilding, and this set is engineered specifically for the engine rebuilder — delivering superior materials and fitment on rebuilt applications where OE gaskets may fall short.

Key Features:

• Designed for the GM/Chevrolet 3.4L (207 CID) OHV V6 engine, 12-valve configuration
• Intake gaskets feature metal torque limiters for improved durability and consistent clamping force
• Head gaskets are no-retorque with virtually no loss in clamping force over time
• Individual gaskets are die-cut from the correct material and precise thickness for this application
• Elastomeric sealing beads in critical areas provide superior sealing performance
• Premium silicone blend coat allows head-to-block movement and facilitates easy removal
• Intake gaskets designed to prevent vacuum leaks and withstand high temperatures from exhaust crossover heat
• Naturally aspirated, gasoline (SFI/MFI) fuel system applications

Installation Note: New head bolts are required for proper installation. Many GM engines of this type use torque-to-yield head bolts that are one-time use only and must be replaced during reassembly.

The Enginetech GM207HS-D delivers the precision and quality engine builders rely on for a confident, leak-free seal on the GM 3.4L V6 platform.
