We not only cut seats for the non-performance market but have also designed specific cutters that we use in all our modern 4-valve heads. Every head is also vacuum-checked after each seat is cut to ensure that no head leaves with a poor sealing valve. We would then typically set and adjust the installed valve tip height to our specs to ensure proper valve train geometry is maintained.\u003c\/li\u003e\n\u003cli\u003eWe also have a resurfacing machine that provides a superior RA, or finishes, on both cast and aluminum blocks and heads, which is crucial for proper head gasket sealing in modern engines. Ours uses the CBN cutters and provides a superior finish to the older, multi-cutter systems that many shops still use.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"newdescrLC\"\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2003-2006 Mitsubishi Evo 8\/9\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's In The Box?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 - Stage 3 Cylinder Head Service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"clear\"\u003e\u003c\/div\u003e","brand":"MAPerformance","offers":[{"title":"Default Title","offer_id":52063354028398,"sku":"MAP EVO-CHS-S3","price":2499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0066\/0370\/2362\/files\/maperformance-map-evo-chs-s3-30968233754694.jpg?v=1747150389","url":"https:\/\/titanmotorsports.com\/es\/products\/map-stage-3-cylinder-head-preparation-evo-8-9","provider":"Titan Motorsports","version":"1.0","type":"link"}
