This gasket features a 4.250-inch bore diameter and a compressed thickness of .025 inches (25 thousandths), making it ideal for custom engine builds where precise compression ratio tuning is critical.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• 4.250-inch bore diameter accommodates specific cylinder configurations
• .025-inch compressed thickness for precise compression control
• Integrated oil and coolant passages ensure proper fluid routing
