Lowest Price GuaranteeFel-Pro 1043 is a performance head gasket for race-oriented small-block Chevy cylinder head combinations where high cylinder pressure and head movement demand a stronger combustion seal. Its steel core laminate construction, Kevlar-reinforced facing, conformable anti-stick coating, and pre-flattened combustion sealing rings help control leaks across imperfect sealing surfaces without relying on a generic stock replacement design.
Fel-Pro 1043 Technical Specifications:
- 4.080 in. bore and .039 in. compressed thickness provide defined gasket dimensions for compression and clearance planning.
- 8.200 cc compressed volume supports accurate engine build calculations when matching chambers, pistons, and deck height.
- Steel core laminate construction with Kevlar-reinforced fiber facing adds strength for demanding racing conditions.
- Pre-flattened steel wire combustion seals concentrate clamping force around each cylinder to help manage high combustion pressure.
- Conformable anti-stick coating helps seal small surface imperfections and supports cleaner service during future teardown.
- Printoseal sealing beads target critical fluid passages to reduce potential leak paths around oil and coolant areas.
Use this gasket when building or refreshing a racing small-block Chevy engine that matches the specified chamber and block requirements. Because the fitment data is application-sensitive, confirm the gasket outline against the cylinder head and block before final assembly.
For small-chamber aluminum race heads and some Vortec applications only. It will not fit conventional OEM-type combustion chambers, cannot be used on aluminum blocks with liners, and is not intended for emission-controlled vehicles. Verify chamber shape, bore, block material, and head design before installation.
Fel-Pro wire ring head gaskets are offered in various bore sizes, thicknesses, and materials to meet any need. Fel-Pro head gaskets are designed to be relied on by the professional racer as well as the Sunday cruiser when it comes to sealing combustion pressure, coolant, and oil under all conditions.

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 Fel-Pro gaskets also offer superior heat dissipation from combustion hot spots.
Loc Wire Ring Head Gaskets
Fel-Pro 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.
