These heads start with high-quality, high-nickel content castings built to withstand the demands of tuned and boosted applications. We've incorporated reinforced injector bores and strengthened bolt holes to eliminate common factory failures like cracking and fuel dilution in the coolant, while hardened valve seat inserts prevent the cracking issues that plague stock heads.\u003c\/p\u003e\n\n\u003cp style=\"text-align: center;\"\u003eEach head undergoes precision CNC porting in-house, optimizing the intake and exhaust runners, bowl areas, and valve seats to achieve up to 30% more airflow compared to stock. This boost in air velocity reduces turbulence, improves combustion efficiency, and unlocks real-world power gains—often 100+ horsepower when paired with supporting mods like larger turbos or injectors, with high-horsepower diesel builds frequently exceeding 900-1,000 hp on ported setups.\u003c\/p\u003e","brand":"Ford","offers":[{"title":"No Thanks \/ 18MM","offer_id":48432844734713,"sku":"RCD-1730190002","price":1799.99,"currency_code":"USD","in_stock":true},{"title":"No Thanks \/ 20MM","offer_id":48432844767481,"sku":"RCD-1735190002","price":1799.99,"currency_code":"USD","in_stock":true},{"title":"Yes \/ 18MM","offer_id":48432844800249,"sku":"RCD-1730190003","price":1974.99,"currency_code":"USD","in_stock":true},{"title":"Yes \/ 20MM","offer_id":48432844833017,"sku":"RCD-1735190003","price":1974.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0808\/3793\/5353\/files\/RCD-6.0L-Head-1_22c1e846-3ddc-4b33-bace-1fc45d7ebda4.jpg?v=1779546227","url":"https:\/\/www.georgiadieselworks.com\/products\/6-0l-ford-cnc-ported-cylinder-head-pre-1-14-06-18mm-dowels-t40-injector-hold-down-bolt","provider":"Georgia Diesel Works","version":"1.0","type":"link"}
