It is made for rebuilt and modified engines where the head seal has to hold more cylinder pressure than a factory gasket.\u003c\/p\u003e\n\u003cp\u003eChoose the thickness to suit your build. It comes in a 93.5 mm bore and thicknesses of 0.7 mm, 1 mm, 1.2 mm or 1.5 mm. A thicker gasket lowers compression and adds piston-to-head clearance, so measure deck height and set the thickness with your engine builder. The thickness shown is Siruda's figure at the combustion seal; the body thickness is in the specifications.\u003c\/p\u003e\n\u003cp\u003eSiruda's stopper design adds a stopper layer sandwiched between the steel layers around each bore. It keeps the combustion seal stable under engine vibration, and the compact seal suits engines with little room around the combustion chamber.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Sold individually: this engine needs two, one for each cylinder head. Installation by a professional is recommended. Engine internals must be measured and set up by a qualified engine builder.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMulti-layer steel (MLS) construction\u003c\/li\u003e\n\u003cli\u003eStopper layer between the steel layers around each bore\u003c\/li\u003e\n\u003cli\u003e93.5 mm bore\u003c\/li\u003e\n\u003cli\u003eChoice of thickness: 0.7 mm, 1 mm, 1.2 mm or 1.5 mm\u003c\/li\u003e\n\u003cli\u003eSuits stock and built engines\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAlso available: \u003ca href=\"\/products\/cometic-mls-head-gasket-subaru-ej20-turbo-ej205-ej20g-93mm-bore\"\u003eCometic MLS Head Gasket (Single) – Subaru EJ20 Turbo EJ205 \/ EJ20G – 93mm Bore\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003ePairs Well With\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/siruda-full-engine-gasket-set-subaru-wrx-sti-grb-ej20\"\u003eSiruda Full Engine Gasket Set - Subaru WRX STI (GRB) - EJ20\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/siruda-exhaust-manifold-gasket-subaru-wrx-wrx-sti-gc8-gd-ge-gh-gr-gv-va-forester-sf-sg-sh-ej-series\"\u003eSiruda Exhaust Manifold Gasket - Subaru WRX \/ WRX STI (GC8 \/ GD \/ GE \/ GH \/ GR \/ GV \/ VA) \/ Forester (SF \/ SG \/ SH) - EJ Series\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/arp-head-stud-kit-subaru-ej20-ej25-dohc-wrx-sti-gc-gd-ge-gh-gr-gv-va-forester-sf-sg-sh-liberty-gt-be-bh-bl-bp\"\u003eARP 2000 Head Stud Kit - Subaru EJ20 \/ EJ25 DOHC - WRX \/ STI (GC \/ GD \/ GE \/ GH \/ GR \/ GV \/ VA) \/ Forester (SF \/ SG \/ SH) \/ Liberty GT (BE \/ BH \/ BL \/ BP)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/supertech-dual-valve-spring-retainer-kit-subaru-wrx-sti-fxt-lgt-ej20-ej25\"\u003eSupertech Dual Valve Spring \/ Retainer Kit - Subaru WRX\/STI\/FXT\/LGT (EJ20\/EJ25)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/king-racing-connecting-rod-bearing-set-subaru-ej20-ej22-ej25\"\u003eKing Racing Connecting Rod Bearing Set – Subaru EJ20 \/ EJ22 \/ EJ25 (Incl.
