Fel-Pro 1037 is a performance head gasket for Big Block Chevy V8 builds using 396, 402, 427, 454, 502, 510, 540, or 572 CID architecture from the classic Mark IV era through later service applications. Its stainless steel core laminate and reinforced combustion seal are built to help control torque loss, resist gasket blowout, and maintain sealing force in high-output street, race, and marine engines.

Fel-Pro 1037 Technical Specifications:

• 4.370 in. bore and .039 in. compressed thickness support common Big Block Chevy performance combinations.
• 9.700 cc compressed volume gives engine builders a known gasket volume for compression-ratio calculations.
• Stainless steel core laminate construction with a PermaTorque blue gasket body helps minimize torque loss under demanding cylinder pressure.
• Pre-flattened wire-ring combustion seats with stainless steel armor add concentrated sealing force around the combustion chambers.
• No lock wire is used, matching the published gasket configuration for this part number.

Includes:

• One head gasket

Use when a performance Big Block Chevy build needs a steel-core head gasket with reinforced combustion sealing rather than a standard replacement gasket. Confirm block preparation, cylinder bore, compressed thickness, and water-jacket requirements before assembly.

Designed for Big Block Chevy Mark IV-style applications and noted as suitable for marine use. Mark IV installations require drilling three additional water jacket holes in the engine block, and 1971 and earlier blocks may require modification.
