Every Delta Series head starts as a brand-new OEM Ford casting and is machined in-house with CAD-designed port profiles on 5-axis CNC equipment, so every port flows the same from cylinder to cylinder.\u003c\/p\u003e\n\u003cp\u003eThe port shapes were developed in CAD using OEM Ford data, including the complete water jacket geometry, which lets KDD port aggressively while holding safe wall thickness in every critical area. Designs are validated with sonic testing and the water jackets are left completely untouched. KDD also worked with airflow specialist Darrin Morgan on the port work.\u003c\/p\u003e\n\u003cp\u003eChoose the model year split that matches your truck and the porting level that matches your build.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePart Numbers:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e67P-CH-532-2: 2011-2019, Level 2\u003cbr\u003e67P-CH-632-2: 2011-2019, Level 3\u003cbr\u003e67P-CH-533-2: 2020+, Level 2\u003cbr\u003e67P-CH-633-2: 2020+, Level 3\u003c\/p\u003e\n\u003ch6\u003eLevel 2 - Mild CNC Port (Factory Plenum)\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eRetains the factory intake plenum\u003c\/li\u003e\n\u003cli\u003eCNC bowl cleanup and accessible intake port work\u003c\/li\u003e\n\u003cli\u003eCNC ported exhaust ports\u003c\/li\u003e\n\u003cli\u003eFactory valves retained\u003c\/li\u003e\n\u003cli\u003eHeavy duty performance valve springs\u003c\/li\u003e\n\u003cli\u003eO-ringed deck surface for better head gasket sealing\u003c\/li\u003e\n\u003cli\u003eIdeal for VGT turbo upgrades, mild S300 and mild compound setups, and high performance daily drivers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch6\u003eLevel 3 - Full CNC Port (Billet Plenum)\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eFactory cast-in intake plenum removed for a complete CNC intake port, including areas the factory plenum blocks\u003c\/li\u003e\n\u003cli\u003eFully CNC ported high flow intake and exhaust ports\u003c\/li\u003e\n\u003cli\u003eBillet aluminum intake plenum included\u003c\/li\u003e\n\u003cli\u003eOversized stainless steel nitrided valves\u003c\/li\u003e\n\u003cli\u003eKDD proprietary valve angles and valve seat profile\u003c\/li\u003e\n\u003cli\u003eCompetition level valve springs\u003c\/li\u003e\n\u003cli\u003eO-ringed deck surface (fire ring available on request)\u003c\/li\u003e\n\u003cli\u003eIdeal for large single turbos, compound turbo systems, nitrous, drag racing and sled pulling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch6\u003eAirflow (Level 3)\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eIntake: approx. 180 CFM stock vs approx. 250 CFM, about a 38% increase, and it keeps flowing past 0.700\" valve lift\u003c\/li\u003e\n\u003cli\u003eExhaust: approx. 160 CFM stock vs approx. 250 CFM, with up to 40% more exhaust port cross-sectional area\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch6\u003eBillet Intake Plenum\u003c\/h6\u003e\n\u003cp\u003eThe factory 6.7L intake port has blind areas behind the cast-in plenum that cannot be ported.
