Evo 123 - Brian Crower - 4G63 Head Gasket (86mm / 0.8mm)

Brian Crower MLS head gasket (86mm bore, 0.8mm) — 4G63T

A multi-layer steel gasket for a boosted 4G63 that is being put back together properly. Individual die-cut stainless layers give it the consistency a composite gasket cannot hold at high cylinder pressure, and a uniform 0.2 micron nitrile rubber coating fills the surface finish of the head and seals as the engine comes up to temperature. Two numbers decide whether this is your gasket: the 86mm bore suits a block that has been taken out past the 85.0mm standard, and at 0.8mm it is on the thin side, which nudges static compression up rather than down. Match both to what your machinist has actually done to the block.
