SBC LT1 Intake Gasket .060in THICK STEEL CORE

The FEL-PRO SBC LT1 Intake Gasket .060in Thick Steel Core (MPN 1284) is a precision-engineered replacement gasket designed for GM LT-series small-block engines from 1992–1997. This intake manifold gasket features a laminated steel core construction with Printoseal facing, engineered to maintain a reliable seal under the thermal and pressure cycles of high-performance engine operation. The 0.06-inch thickness and rectangular port configuration (1.25 x 2.04 inches) are matched to OEM specifications for the LT1 platform.

The steel core laminate construction provides superior durability compared to single-layer gasket materials. The laminated design resists warping and deformation under sustained load, critical for maintaining intake manifold seal integrity on high-output LT1 engines that generate significant combustion pressures. The Printoseal facing ensures chemical compatibility with modern coolant formulations and gasoline, preventing degradation over extended service intervals. At 0.36 lbs, this gasket kit offers the dimensional precision required for proper intake plenum sealing without adding unnecessary bulk to the assembly.

This gasket is the correct choice for owners rebuilding or servicing GM LT1 engines, whether for street performance, off-road applications, or racing. Technicians and enthusiasts routinely specify FEL-PRO gaskets for LT-series engine work because the brand's laminated construction directly addresses the most common failure mode in aged small-blocks: intake manifold leaks caused by gasket compression and thermal cycling. The rectangular port design ensures proper sealing across the fuel injector boss areas and coolant passages without interference or misalignment during installation.
