PRC CNC Porting Service – Customer Supplied 6.2L or 6.4L Apache/Hellcat Hemi Cylinder Heads By Texas Speed

Ready to give your Hemi the power it’s been dreaming of? Say goodbye to factory limitations and hello to serious performance gains with our CNC Porting Service for 6.2L/6.4L Hemi cylinder heads. We’re not just talking about making your engine look cooler—we’re talking about unleashing the beast under the hood, adding over 30 horsepower in some cases! Our secret? Precision CNC porting that makes your engine flow like it’s got a VIP pass to the fast lane.

Here at Texas Speed & Performance, we’ve got more CNC machines than most people have pairs of socks (okay, maybe not that many, but we do have 25+ machines dedicated to late-model performance parts). That means we can get your heads ported and back to you faster than you can say “I want more horsepower!” Plus, we’re all about giving you top-tier performance without charging you the infamous “Hemi tax” that other shops might try to sneak in.

So, what do you get when you send us your cylinder heads? First, we take them in for a tear-down, cleaning, and thorough inspection. After that, we unleash our CNC magic: 5-axis CNC porting for intake and exhaust runners, CNC chamber machining, and hand blending to make sure everything flows just right. We also offer optional PAC Racing valve springs for those looking to go even harder. The results? A factory cylinder head that performs like an aftermarket powerhouse.

For the record, this isn’t just for show. You’ll see real dyno results, with flow numbers hitting 392 CFM on intake and 245 CFM on exhaust. It’s time to stop talking about power and start feeling it!
