Vehicle Info NeededMulti-Layer Steel Core Head Gasket, 4.125 in. Bore, 0.039 in. Thick for 1992-1997 GM 5.7L LT1 and LT4 Vehicles
Ships on 11/25/2026
Lowest Price GuaranteeFel-Pro 1074 is a high-performance head gasket for GM Gen II Small Block Chevy 5.7L V8 LT1 and LT4 engines, built to seal hard-working street and performance combinations where cylinder pressure and head movement can overwhelm a basic gasket. Its multi-layer stainless steel core laminate, wire-ring combustion seal, and anti-friction coating help control combustion sealing and fluid sealing on real-world surfaces while supporting verified applications such as Corvette, Camaro, Firebird, Impala SS, Roadmaster, and Fleetwood platforms from the LT1 and LT4 era.
Fel-Pro 1074 Technical Specifications:
- 4.125 in. bore and .039 in. compressed thickness match common LT1 and LT4 Gen II Small Block Chevy 5.7L V8 performance builds.
- 8.700 cc compressed volume gives engine builders a known gasket volume for compression ratio planning.
- Multi-layer stainless steel core laminate and a solid-steel core help reduce torque loss and resist combustion-gas blowout.
- Wire-ring combustion seat with stainless steel armor focuses clamp load around the chamber for high cylinder-pressure sealing.
- Pre-flattened copper and steel wire-ring construction is designed to seal without brinelling aluminum cylinder heads.
- KEVLAR fiber reinforcement is specified for severe combustion pressure environments rated in the research context at 1,500 to 3,000 PSI.
- Embossed Printoseal sealing beads help close off leak paths around oil and coolant passages on imperfect service surfaces.
- Nonstick anti-friction coating helps seal small surface flaws and makes gasket removal cleaner during future teardown work.
- Steel-core construction is designed to eliminate cylinder head bolt retorque after installation.
Suited for demanding naturally aspirated and power-adder LT1 and LT4 builds, including supercharged, turbocharged, and nitrous combinations described in the research context. The gasket is also noted for high-output engines up to 1,000 horsepower when the rest of the engine package and fastener setup are appropriate.
Verified fitment centers on 1992-1996 Chevy Corvette, 1993-1997 Chevy Camaro, 1993-1997 Pontiac Firebird, 1994-1996 Chevy Impala SS, 1994-1996 Buick Roadmaster, and 1994-1996 Cadillac Fleetwood models equipped with the 5.7L LT1 or LT4 Gen II Small Block Chevy V8. Confirm bore, cylinder head material, block configuration, and build requirements before installation.
Pre-Flattened Steel Wire Ring Head Gaskets
The strength of steel wire sealing with minimum brinelling of aluminum heads.
Pre-Flattened Copper Wire Ring Head Gaskets
Copper will not brinell aluminum heads, and these gaskets also offer superior heat dissipation from combustion hot spots.
Loc Wire Ring Head Gaskets
Loc Wire gaskets are engineered to provide the best sealing available for severe applications. They have oversized wire rings that lock into receiver grooves which must be machined into the cylinder heads. Precise machining is critical to the success of these gaskets.
