It has a 100mm round bore and comes in a choice of compressed thicknesses, so you can match the stock deck height or set the compression ratio on a rebuilt engine.\u003c\/p\u003e\u003cp\u003eCometic's MLS (multi-layer steel) gasket is built from embossed stainless steel layers, with high-temperature coated outer layers that seal against the head and block. Because the overall thickness comes from the centre layer, Cometic can offer many thicknesses, which makes MLS the go-to for setting compression ratio or squish on a built engine.\u003c\/p\u003e\u003ch3\u003eOptions\u003c\/h3\u003e\u003cp\u003eCompressed thickness: 0.76mm (.030\"), 1.14mm (.045\"), 1.52mm (.060\"). Thicker gaskets lower compression; match the thickness to your engine builder's spec.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Sold individually – an EJ engine needs two, one for each head. For EJ255 and EJ257 engines from 2007, choose the 101mm Version 2 gasket instead.
