Complete CNC Dual Spring Cylinder Head Set By Thitek

Get ready to supercharge your GenIII Hemi with our Thitek CNC Ported & Assembled Cylinder Heads! These heads are like a performance spa day for your engine—fully prepped, assembled, and ready to bolt on with zero fuss. Forget about any awkward modification dances; these heads slip right into place, making your ride the envy of the track.

Our dual spring version comes fully loaded with PSI 1512 dual springs, titanium retainers, and solid stem intake and exhaust valves. We’ve even thrown in bronze guides, ductile iron seats, and Viton valve seals to round out the package. These heads aren’t just about good looks; they’re engineered for serious power and reliability.

Choose from our port programs: 200cc with a 2.125” valve, 205cc with a 2.165” valve, or the impressive 210cc with a 2.200” valve. All models feature a 1.650” exhaust valve, a 5-angle intake valve job, and a radius exhaust valve job, each with a 45-degree seat and back cut on the intake valve. Translation? Your engine’s airflow will be smoother than a fresh jar of peanut butter.

We’ve cranked up the airflow, too, with gains from over 75 cfm on the 200cc heads to a whopping 100 cfm on the 205cc. Plus, the high-flow exhaust port design boosts airflow by over 50 cfm compared to stock heads. The result? You’ll see performance gains of over 50 rear wheel horsepower and drop a full second off your quarter-mile time. And don’t worry about head gaskets giving up under high boost—these heads have got you covered.

So if you’re ready to ditch the factory limitations and push your engine to the max, grab these Thitek heads and let the performance magic begin!

THERE IS AN LONG WAIT TIME ON CYLINDER HEADS. THEY ARE MADE TO ORDER AND CAN TAKE UPTO 6 MONTHS.
