Description

Features & Benefits: 4.500in. Bore, MLX 0.040in. thick Head Gaskets (Multi-Layer-Xtreme). Our MLX Gasket (Multi-Layer-Xtreme) features an extra ‘stopper’ fold-over layer providing a torque limiting surface that prevents yielding of the combustion seal. Tech Tips: Use of these head gaskets without proper clearance checks on these custom built/spec motors can lead to catastrophic engine failure. Remember to check your clearances! ALL bores over 4.250in. on Oil Cooled Heads must have the Oil Holes Welded.
