Passenger Side 185CC As-Cast Street Hawk Cylinder Head By Air Flow Research

Looking to replace your stock Gen III HEMI head with something that won’t roll over and play dead the minute you turn up the boost? Say hello to AFR’s 185cc As-Cast Black Hawk Aluminum Cylinder Head—your engine’s new best friend and your power goals’ secret weapon.

Built from rugged A356 aluminum using permanent mold wizardry (seriously, this stuff is forged in nerd fire), this head features a meaty .750” deck thickness to keep things from going boom when you really lean on the throttle. It’s basically the gym rat of cylinder heads—muscular, dependable, and cooler under pressure than your cousin at Thanksgiving dinner.

AFR didn’t just make this thing strong—they made it smart. Improved water jacket design means better cooling even when the heat is on, and we’re keeping a solid .200” of meat between ports and water for peace of mind. Got a Hellcat blower in your future? There’s even a machine option to make that dream come true. Boom.

Designed for hydraulic roller cams up to .600” lift, this fully assembled beauty comes stacked with PAC Racing springs, CNC’d combustion chambers, 5-angle valve job, bronze guides, chrome moly retainers—the works. Honestly, the parts list reads like a who’s who of valvetrain royalty.

Want flow numbers? Oh yeah—we got those. This head breathes better than your yoga instructor. See the flow chart and get ready to say goodbye to backpressure.

Just don’t forget—this listing is for one head. If your engine has two (which… it probably does), grab a matching passenger side and make it a set!
