Welcome to the next level of Hemi performance with our Thitek CNC Ported & Assembled Cylinder Heads! These heads are like the VIP pass for your GenIII Hemi—ready to drop into place without any pesky modifications. Just bolt them on and watch your engine transform from mild to wild.
Our Beehive version is equipped with PSI 1511 beehive springs, titanium retainers, and solid stem intake and exhaust valves. We’ve also included bronze guides, ductile iron seats, and Viton valve seals to make sure everything runs as smoothly as your favorite dance moves. These heads are designed to be a perfect fit, so you won’t need to pull out your toolbox and make any adjustments—just install and go!
Pick your port program: 200cc with a 2.125” valve or 205cc with a 2.165” valve. Both options come with a 1.650” exhaust valve and feature a 5-angle intake valve job and a radius exhaust valve job, all with a 45-degree seat and a back cut on the intake valve. Translation? You’ll get airflow that’s smoother than a baby’s bottom and performance that’ll make your engine purr like a kitten… or roar like a lion, depending on your mood.
We’ve cranked up the airflow from 75 cfm on the 200cc heads to an impressive 100 cfm on the 205cc heads. And let’s not forget the high-flow exhaust port design, which boosts airflow by over 50 cfm compared to factory heads. You’ll see gains of over 50 rear wheel horsepower and drop a full second off your quarter-mile time. Plus, these heads can handle higher boost levels, keeping those head gaskets where they belong—secure and unruffled.
