CAPTION THIS. If you’ve dealt with Kill Devil Diesel for any length of time, there’s a pretty good chance you’ve met Michael Doyle (the one on the right) Cylinder head production, engine machining, customer service, trade shows… Doyle’s been around here long enough to know better 😂😂 He’s currently down in Texas for the NHRDA World Finals, hanging out with our buddies at Knox Diesel. And somehow… this picture made its way back to us. We have questions. 😂 We’ll let y’all handle this one. Best caption wins. Doyle — care to explain?

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
