They have 1-7\/8\" square exhaust ports and 17-7\/8\" center-to-center spacing on the outer bolt holes. Speed Engineering designed them for high cylinder pressures, states that they hold their torque and resist corrosion, burn-through, and push-out, and notes that they work with different combinations of cylinder head and exhaust manifold materials.\u003c\/p\u003e\u003cp\u003eIncludes 2 gaskets.\u003c\/p\u003e\u003cblockquote\u003e\n\u003cp\u003e⚠️ \u003cstrong\u003eImportant Notes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBBC engines only\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/blockquote\u003e\u003chr\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eMulti-Layer Steel (MLS) Construction\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e1-7\/8\" Square Exhaust Ports\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e17-7\/8\" Center-to-Center Outer Bolt Holes\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eHolds Torque and Resists Corrosion\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eQuantity: 2 Exhaust Manifold Gaskets\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBBC Engines Only\u003c\/strong\u003e: 6.5L, 6.6L, 7.4L\u003c\/li\u003e\n\u003c\/ul\u003e\u003chr\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat type of gasket is this?\u003c\/h5\u003e\u003cp\u003eIt is a multi-layer steel (MLS) exhaust manifold gasket.\u003c\/p\u003e\u003ch5\u003eWhich engines do these gaskets fit?\u003c\/h5\u003e\u003cp\u003eThey are for BBC engines only (6.5L, 6.6L, 7.4L).\u003c\/p\u003e\u003ch5\u003eWhat port size and bolt spacing do they have?\u003c\/h5\u003e\u003cp\u003eThey have 1-7\/8\" square exhaust ports and 17-7\/8\" center-to-center spacing on the outer bolt holes.\u003c\/p\u003e\u003ch5\u003eHow many gaskets are included?\u003c\/h5\u003e\u003cp\u003eThe set includes 2 exhaust manifold gaskets.\u003c\/p\u003e\u003ch5\u003eDo these gaskets work with different head and manifold materials?\u003c\/h5\u003e\u003cp\u003eYes.
