A major advantage of conical springs vs. traditional cylindrical or beehive springs is the damping and removal of valvetrain harmonics.\u003cbr\u003e\u003cbr\u003eOf the three designs, conical springs are the front runners in valvetrain harmonic stability. Utilizing a varying coil diameter as well as coil spacing, a conical spring acts as a natural harmonic damper in the transfer of valvetrain shock. This translates to less stress, less wear, and a longer life of the included components.\u003cbr\u003e\u003cbr\u003eThis level of protection is needed in today’s engines being pushed to their physical and mechanical limits by aftermarket modifications. Every GSC conical spring offers a super finished surface treatment to go along with the patented, multi-step heat treatment process.

GSC flow tests prototype valve heads in the specific applications to ensure the highest flowing valve head available on the market today. With the materials used, GSC offers less valve distortion at the face than any of the tested designs. Less distortion allows for better sealing under extreme conditions and more consistent performance throughout the life of the valve.\u003cbr\u003e\n\u003cul\u003e\n\u003cli\u003eSwirl polished heads for smoother air flow over the valve\u003c\/li\u003e\n\u003cli\u003eBack cut to reduce valve weight for higher RPM, higher boost pressure, and allow for more aggressive cam profiles without increasing valve spring seat pressures\u003c\/li\u003e\n\u003cli\u003eValve stems are micro polished to allow for less oil retention on the stem, which creates less drag on the stem to guide for a smoother motion\u003c\/li\u003e\n\u003cli\u003eIntake valves are a modified 21-4n stainless and exhausts are a modified 23-8n stainless material for high heat capacity while maintaining longevity\u003c\/li\u003e\n\u003cli\u003eValve tips are either hardened or have a stelite wafer tip fused so that the tip is within 5 Rockwell C of the rocker or valve tappet for extended life and less wear\u003c\/li\u003e\n\u003cli\u003eValve tip lengths - GSC takes extra time to adjust tip heights on the applications to require less tipping of the valve, to maintain proper tip height for proper valve train geometry, and to cut down on install times when setting valve lash\u003c\/li\u003e\n\u003cli\u003eGSC has also adjusted the keeper groove to properly balance intake and exhaust spring pressures to reduce the use of valve spring shims and maximize performance from GSC spring and retainer kits\u003c\/li\u003e\n\u003cli\u003eValves will work with an OEM keeper\/lock or, when available, GSC upgraded keeper\/lock.

With performance and aftermarket installation in mind, we hold extremely tight tolerances on through-hole concentricity to outside diameter which minimizes the required honing time for the installer. True-to-size outside diameters minimize honing of guide bosses on cylinder heads that don't require boss service. Our guides are easier to install and shaped to improve air flow instead of just copying OEM design.\u003cbr\u003e\u003cbr\u003e\n\u003cdiv style=\"overflow-x: auto;\"\u003e\n\u003ctable cellspacing=\"0\" cellpadding=\"0\" border=\"0\"\u003e\n\u003ctbody\u003e\n\u003ctr bgcolor=\"2d2d2d\"\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003ePart Number:\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003eSize:\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003eQuantity:\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"404040\"\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003eGSC3088-8\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003eStandard\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003eSet of 8\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"2d2d2d\"\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003eGSC3088\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003eStandard\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003e1 Guide\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"404040\"\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003eGSC3088.001-1\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003e+.001\"\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003e1 Guide\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"2d2d2d\"\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003eGSC3088.003-1\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003e+.003\"\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"color: #ffffff;\"\u003e1 Guide\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003ca style=\"color: #afafaf;\" href=\"https:\/\/stmtuned.com\/collections\/gsc-power-division-products\"\u003e\u003cbr\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cspan style=\"font-size: .8em;\"\u003e\nSee more GSC Products\u003c\/span\u003e\u003c\/div\u003e\u003c\/a\u003e","brand":"GSC","offers":[{"title":"Standard Set of 8 (GSC3088-8)","offer_id":50562782069078,"sku":"GSC-3088-8","price":44.57,"currency_code":"USD","in_stock":true},{"title":"Standard Single Guide (GSC3088)","offer_id":50562782101846,"sku":"GSC-3088","price":8.3,"currency_code":"USD","in_stock":true},{"title":"'+.001\" Single Guide (GSC3088.001-1)","offer_id":50562782134614,"sku":"GSC-3088.001-1","price":8.3,"currency_code":"USD","in_stock":true},{"title":"'+.003\" Single Guide (GSC3088.003-1)","offer_id":50562782167382,"sku":"GSC-3088.003-1","price":8.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/9531\/8102\/files\/GSC3088-gsc-honda-s2000-intake-valve-guides-set-of-8.jpg?v=1749204716"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/9531\/8102\/collections\/GSC_large_logo.png?v=1779877127","url":"https:\/\/www.speed-addicts.com\/en\/collections\/gsc.oembed","provider":"Speed Addicts","version":"1.0","type":"link"}
