The factory head gasket on these\n  engines wasn't built with a lot of margin, and once you're on boost or spinning it past where Honda\n  intended, that factory gasket is one of the first things to give up on you. This is Cometic's 75.5mm,\n  .030 inch MLS gasket for the D16Z6, D16Y7, and D16Y8, and it's three layers of stainless steel where\n  your factory composite used to be. It's a gasket that's actually built for what you're asking the\n  engine to do.\n\u003c\/p\u003e\n\n\u003ch4\u003eHere's How You Know Your Factory Gasket's Done\u003c\/h4\u003e\n\u003cp\u003e\n  The signs aren't subtle once they show up. You'll see white smoke from the exhaust, coolant mixing into\n  the oil, a coolant leak you can't track down, or a temperature gauge that climbs for no obvious reason.\n  Any one of those means the head gasket's gone, and by the time you're seeing them, there's a real chance\n  the head's warped too. Replacing a blown gasket is one thing; replacing a gasket and a warped head is a\n  completely different bill. Get the MLS gasket in before that happens, especially if you've already\n  added boost or turned the engine up, and you don't have to find out the hard way.\n\u003c\/p\u003e\n\n\u003ch4\u003eThree Layers Of Stainless, Viton Coated And Built To Stay Sealed\u003c\/h4\u003e\n\u003cp\u003e\n  Here's what you're actually getting. Three layers of stainless steel, outer layers embossed and coated\n  with Viton rated to 482°F, and an uncoated stainless center shim in the middle. The Viton coating keeps\n  the outer layers from degrading around oil and coolant, and the embossing is what locks the seal in\n  place without any sealant. You don't add anything, you just install it and it does the job. The D-series\n  is an aluminum head on a cast iron block, which creates shearing forces between the two materials as\n  they heat and cool at different rates. MLS construction handles that, where a composite gasket\n  eventually can't.\n\u003c\/p\u003e\n\n\u003ch4\u003eNo Re-Torque, So You're Done When You're Done\u003c\/h4\u003e\n\u003cp\u003e\n  Once you torque the head bolts to spec, you're finished. The embossing design spreads the clamp load\n  evenly across the whole sealing surface, so you're not coming back a few hundred miles later to\n  re-torque the head bolts and risk uneven clamping. It's one of those small things that matters a lot\n  when you're in the middle of a build and you've already got enough to keep track of.\n\u003c\/p\u003e\n\n\u003ch4\u003e75.5mm Is A Common D16 Overbore, So Make Sure It's Yours\u003c\/h4\u003e\n\u003cp\u003e\n  The stock D16 bore is 75mm, so this 75.5mm gasket is built for a block that's been bored 0.5mm over.\n  If your block is still at stock bore, you'd want the 75mm version instead, not this one. And if you've\n  milled the head or you're chasing a specific compression ratio, Cometic makes this gasket in .040 and\n  .051 inch thicknesses too, so you can match the thickness to your actual deck height instead of just\n  going with the default. Match the bore and thickness to your build before you order, and you're set.\n  If you're already in here pulling the head, now's the time to swap in ARP head studs too. Stock head\n  bolts stretch under boost, and studs keep your clamping consistent so you're not back in here again\n  sooner than you planned.\n\u003c\/p\u003e\n\n\u003ch4\u003eWhat You Get\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCometic MLS head gasket (C4251-030) for the D16Z6, D16Y7, and D16Y8\u003c\/li\u003e\n  \u003cli\u003e75.5mm bore, .030 inch compressed thickness\u003c\/li\u003e\n  \u003cli\u003e3 layers of stainless steel for strength and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eViton coating on outer layers, heat resistant to 482°F\u003c\/li\u003e\n  \u003cli\u003eEven clamp load embossing, no re-torque needed after install\u003c\/li\u003e\n  \u003cli\u003eBuilt for aluminum head to cast iron block applications\u003c\/li\u003e\n  \u003cli\u003eNo additional sealant required\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFits These Cars\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1992-1995 Honda Civic EX\/Si (D16Z6)\u003c\/li\u003e\n  \u003cli\u003e1993-1995 Honda Del Sol Si (D16Z6)\u003c\/li\u003e\n  \u003cli\u003e1996-2000 Honda Civic CX\/DX\/LX (D16Y7)\u003c\/li\u003e\n  \u003cli\u003e1996-2000 Honda Civic EX (D16Y8)\u003c\/li\u003e\n  \u003cli\u003e1996-1997 Honda Del Sol S (D16Y7)\u003c\/li\u003e\n  \u003cli\u003e1996-1997 Honda Del Sol Si (D16Y8)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\n  Note: Cometic MLS head gasket (part number C4251-030) for the Honda D16Z6, D16Y7, and D16Y8, 75.5mm\n  bore, .030 inch compressed thickness. Built from 3 layers of stainless steel with outer layers embossed\n  and coated in Viton, heat resistant to 482°F, for strength, corrosion resistance, and a seal that holds\n  through repeated heat cycles. Designed for aluminum head to cast iron block applications and requires no\n  additional sealant. The embossing design distributes clamp load evenly, so no re-torque is needed after\n  installation. The 75.5mm bore is for a 0.5mm overbore from the stock 75mm D16 bore, confirm your block\n  has been machined to this size before ordering. Also available in .040 and .051 inch thicknesses for\n  milled head applications. Fits the 1992-2000 Honda Civic and 1993-1997 Honda Del Sol on the applicable\n  D16 engines listed above.
