Driver Side 195CC Street CNC Streek Hawk Cylinder Head By Air FLow Research

Whether you’re looking to wake up your daily driver or add some zing to your weekend cruiser, the AFR 195cc Street Hawk Cylinder Head is the no-nonsense performance upgrade your Gen III HEMI’s been begging for (probably in Morse code through lifter ticks).

Designed for 5.7L and 6.1L setups that want real gains without needing a NASA budget or a race trailer, this head strikes the perfect balance between streetable manners and strip-worthy performance. CNC-ported intake runners, exhaust ports, and combustion chambers give you smoother airflow than a bald eagle riding a tailwind.

Made from A356 aluminum using AFR’s permanent mold tech (that’s fancy talk for “really well cast”), this head comes with a thick .750” deck to handle boost, nitrous, or just your cousin’s hot takes at the local car meet. Cooling channels have been optimized to keep temps in check—even when you’re deep into the skinny pedal.

Loaded with quality components like PAC Racing springs, titanium retainers, and bead lock valves, it’s ready to spin to 6500 RPM with a hydraulic roller cam up to .600″ lift. Basically, it’s like strapping a leaf blower to your engine, but it actually works.

Pro tip: This listing is for one head (driver side). Engines typically require two. Unless you’re building a very confused single-cylinder V8, don’t forget to snag the passenger side too.
