This isn't a one-off. We make these every day. 🔥 Here's a run of our Delta Series Stage 3 CNC ported 6.7 Powerstroke heads moving through production, from brand new castings to finished machine work. They've quickly become one of the most popular products we've ever made. Every head starts as a brand new, 100% OEM Ford casting. We cut the intake shelf off so we can get in and do a proper port job, then bolt our billet plenums back on. That means they still take your factory valve covers and intake manifold. Proven with a head swap only, with no tuning changes and nothing else touched: ✅ 66mm turbo: +25 HP ✅ 80mm turbo: +50 HP ✅ 94mm turbo: +80 HP Customers keep telling us about the spool-up. Guys who needed a lot of nitrous to light their turbo now spool it with none. Guys who couldn't get it to spool at all now do it with just a little. These are the same heads that top off our Outlaw engine package. They're in constant production, so if you want a set, give us a call or order on the site. #killdevildiesel #67powerstroke #powerstroke #cylinderheads #cncported #dieselperformance #fordpowerstroke #dieseltrucks

NEW from Kill Devil Diesel 🔥 Screw-in freeze plugs are now available on our engine packages! It was an honor to machine this 6.0L Power Stroke block for Riffraff Diesel and their GTR Pikes Peak build. Their high-RPM, high-water-pressure application called for something beyond the traditional press-in plug—so we CNC-machined the block for -20 ORB screw-in plugs. Threaded, O-ring sealed, easily serviceable, and designed to stay put under extreme pressure. Race-bred development that’s now available to every KDD customer. 💪
