RWA 1578-32 is .032" thick and designed for the "Pinto" 2.0 OHC engine. Not all solid copper gaskets are created equal. Our 1578-32 is manufactured by SCE and uses premium 99% pure copper sheets rolled to our specifications (choice of 12 different thicknesses) and tested for uniform flatness to assure precise cylinder head-to-block alignment and eliminate uneven loading. After processing, each gasket is annealed to ensure optimum mating and provide measurable gains in cylinder sealing, as evidenced by lower leak-down percentages. O-ringing recommended. 1. Before installing the gasket, perform a visual check to insure that no damage occurred during shipping, the gasket(s) should be flat and free of scratches. 2. SCE Copper head gaskets are annealed in a vacuum oven after punching to provide soft malleable gaskets which are ready to use, do not use a torch to soften the gaskets. 3. Pro Copper series head gaskets (P prefix) require the use of a sealant for coolant and oil passages and o-ring combustion seals installed in the head or block. (P/N 31542 o-ring kit). 4. If you are installing o-rings make sure that the o-ring diameter and location accommodates both bore opening and combustion chamber shape. This will determine the minimum inside diameter of the o-ring. 5. If the combustion chamber or bore is so large that o-rings must be placed less than .100” apart between cylinders, it is advisable to use a “figure 8” pattern for o-rings (see figure #2). This allows for more even clamp load over the entire head surface. 6. Recommended o-ring protrusion is not more than 25% of gasket thickness. Example: Gasket thickness .043”, o-ring height is .008” to .010”. Gasket thickness .050”, o-ring height is .010” to .012”. NOTE: For extreme boost or heavy nitrous an O-ring-Receiver-Groove arrangement is recommended (see figure #3). When using a receiver-groove the wire may be higher than 25% of gasket thickness; wire height & width determines receiver groove depth & width by maintaining the relationships in the figure 3 illustration. 7. Good engine building practice requires clean flat surfaces and clean head bolt threads. If threads are tapped through the deck, use care in sealing threads to prevent coolant migration up the bolt. 8. As with any performance application it is strongly recommended that head bolts be re-torqued. Run the engine to operating temperature, shut down and allow it to cool completely. With the engine cold, follow the recommended torque sequence, one bolt at a time back the fastener off just enough to relieve the friction set, then re-torque to specification. -

RWA1582-40 is manufactured by Cometic and uses their MLS process. Multi Layer System. Cometic MLS head gaskets are constructed from multiple layers of stainless steel for strength and contain load-controlled embossments that conform load distribution across the sealing area. This creates an exceptional seal by requiring less clamp load--resulting in less bore distortion. The stainless steel outer layers utilizing FKM (Viton®) rubber coating, a high-temperature and chemical-resistant polymer. A topcoat of PTFE aids in resistance to fret and increased cold sealing. MLS head gaskets are available for most aftermarket cylinder heads; as with all of Cometic's MLS head gaskets, no sealants or re-torque is required. Bore (in): 3.642 in. Bore (mm): 92.500mm Gasket Material: Multi-layer stainless steel Compressed Thickness (in): 0.040 in. Compressed Volume (cc): 6.828cc Lock Wire: No -
