The 6.7L Cummins Cylinder Head was designed to supersede the 5.9L Cylinder Head. For your ease and ours, PDD only offers 6.7L Cummins Cylinder Heads due to their ability to work on both, just be sure to use the correct model year of head gasket that matches the cylinder block of your application.\u003c\/p\u003e\n\u003cp\u003eStock\u003cspan\u003e \u003c\/span\u003eCummins\u003cspan\u003e \u003c\/span\u003eheads are notorious for dropping valve seats as they accumulate hard miles from heavy towing or street hot rodding. The solution is hardened and oversized valve seats that won’t drop when you’re hauling or hot rodding! Each PDD Stage 2 Hot Street ported cylinder head is upgraded with hardened and oversized press-in valve seats, then Stage 2 CNC ported for a nearly 30% increase producing 217 CFM intake flow and 229 CFM exhaust flow. Fire-ring grooves are then cut with CNC precision producing perfect 4.550\" fire-ring grooves. The heads are then finished up with a multi-angle valve job, new stock sized valves, new valve guide liners, and fully assembled with locks, retainers, new valve seals, and upgraded with PDD 4.5K performance valve springs.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Baker Diesel Performance","offers":[{"title":"Default Title","offer_id":43873380565078,"sku":null,"price":3525.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0704\/3465\/2246\/files\/IMG_7124_e0a07b51-13be-4df8-99ef-19f403846ef3.webp?v=1769949316","url":"https:\/\/baker-diesel-performance.myshopify.com\/products\/power-driven-stage-2-hot-street-cnc-ported-cylinder-head-for-03-18-cr-5-9l-6-7l-cummins","provider":"Baker Diesel Performance ","version":"1.0","type":"link"}
