Fel-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.
