These heads receive Power Driven’s hot street port job, enlarged pushrod holes for better clearance and improved oil drainback, and threaded freeze plugs for reliable operation at high rpm. In addition, every CNC-ported Power Driven cylinder head is machined for compatibility with our Doweled Batwing Rocker Pedestals. After porting, valve and seat work is performed to optimize overall port flow and ensure optimal valve sealing. This head is then assembled by our expert technicians with OEM top-hat-style seals and street conical valve springs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis head is available in 2 options:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e• The “O-Ringed” option is O-ringed to provide the ultimate seal possible with an OEM-style head gasket.\u003c\/p\u003e\n\u003cp\u003e• The “Fire-Ringed” option is machined for fire rings to provide the ultimate seal possible with a fire-ring head gasket.\u003c\/p\u003e\n\u003cp\u003eThe Power Driven hot street port is a moderate CNC port job that creates balanced flow across all 6 cylinders while providing large flow gains with OEM-sized valves. On our SuperFlow 1020 test bench, this port produced a 48% increase on the intake and a 46% increase on the exhaust. This port flows an incredible 195 CFM on the intake and 203 CFM on the exhaust at 28\".\u003c\/p\u003e\n\u003cp\u003eIn real-world back-to-back dyno testing on an 800 hp street truck, the higher flow from this hot street port showed a 75 hp gain versus the baseline stock head. Although a bigger-than-stock camshaft is not required, this port really shines when combined with an aftermarket camshaft with larger-than-stock duration and lift. If your goal is a 1,000-hp street-driven Cummins, this is the head for you!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatible with:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli style=\"list-style-type: none;\"\u003e1989 Dodge 5.9L 12v Cummins\u003c\/li\u003e\n\u003cli style=\"list-style-type: none;\"\u003e1990 Dodge 5.9L 12v Cummins\u003c\/li\u003e\n\u003cli style=\"list-style-type: none;\"\u003e1991 Dodge 5.9L 12v Cummins\u003c\/li\u003e\n\u003cli style=\"list-style-type: none;\"\u003e1992 Dodge 5.9L 12v Cummins\u003c\/li\u003e\n\u003cli style=\"list-style-type: none;\"\u003e1993 Dodge 5.9L 12v Cummins\u003c\/li\u003e\n\u003cli style=\"list-style-type: none;\"\u003e1994 Dodge 5.9L 12v Cummins\u003c\/li\u003e\n\u003cli style=\"list-style-type: none;\"\u003e1995 Dodge 5.9L 12v Cummins\u003c\/li\u003e\n\u003cli style=\"list-style-type: none;\"\u003e1996 Dodge 5.9L 12v Cummins\u003c\/li\u003e\n\u003cli style=\"list-style-type: none;\"\u003e1997 Dodge 5.9L 12v Cummins\u003c\/li\u003e\n\u003cli style=\"list-style-type: none;\"\u003e1998 Dodge 5.9L 12v Cummins\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cp\u003e*May not work for all builds due to other engine\/vehicle modifications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable class=\"woocommerce-product-attributes shop_attributes\"\u003e\n\u003ctbody\u003e\n\u003ctr class=\"woocommerce-product-attributes-item woocommerce-product-attributes-item--weight\"\u003e\n\u003cth scope=\"row\" class=\"woocommerce-product-attributes-item__label\"\u003eWeight\u003c\/th\u003e\n\u003ctd class=\"woocommerce-product-attributes-item__value\"\u003e137 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"woocommerce-product-attributes-item woocommerce-product-attributes-item--dimensions\"\u003e\n\u003cth scope=\"row\" class=\"woocommerce-product-attributes-item__label\"\u003eDimensions\u003c\/th\u003e\n\u003ctd class=\"woocommerce-product-attributes-item__value\"\u003e33 × 15 × 7 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"woocommerce-product-attributes-item woocommerce-product-attributes-item--attribute_head-option-select-an-option-to-see-whats-included\"\u003e\n\u003cth scope=\"row\" class=\"woocommerce-product-attributes-item__label\"\u003eHead Option (Select an option to see what's included)\u003c\/th\u003e\n\u003ctd class=\"woocommerce-product-attributes-item__value\"\u003e\n\u003cp\u003e12v Cummins Stage 2 O-Ringed Cylinder Head, 12v Cummins Stage 2 Fire-Ringed Cylinder Head\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"woocommerce-product-attributes-item woocommerce-product-attributes-item--attribute_extended-warranty\"\u003e\n\u003cth scope=\"row\" class=\"woocommerce-product-attributes-item__label\"\u003eExtended Warranty\u003c\/th\u003e\n\u003ctd class=\"woocommerce-product-attributes-item__value\"\u003e\n\u003cp\u003eNo Extended Warranty, 1-Year Extended Warranty, 2-Year Extended Warranty, 3-Year Extended Warranty\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eThis product cannot ship to California\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003eCheck out the PDD Youtube for anything and everything diesel performance!\u003c\/p\u003e\n\u003cdiv style=\"position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%;\"\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/SlHCqN_gsPo?autoplay=1\u0026amp;mute=1\u0026amp;playsinline=1\u0026amp;rel=0\u0026amp;modestbranding=1\" title=\"YouTube video player\" style=\"position: absolute; top: 0; left: 0; width: 100%; height: 100%;\"\u003e\n  \u003c\/iframe\u003e\u003c\/div\u003e","brand":"Power Driven","offers":[{"title":"12v Cummins Stage 2 O-Ringed Cylinder Head","offer_id":54517592785171,"sku":"51002022014","price":2890.0,"currency_code":"USD","in_stock":true},{"title":"12v Cummins Stage 2 Fire-Ringed Cylinder Head","offer_id":54517592817939,"sku":"51002022024","price":2840.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0957\/1434\/5235\/files\/Power-Driven-Diesel_-Cylinder-Head-Ported_01_0525.jpg?v=1785555113","url":"https:\/\/coltcams.com\/products\/power-driven-stage-2-hot-street-cnc-ported-cylinder-head-for-89-98-12v-cummins","provider":"Colt Cams","version":"1.0","type":"link"}
