“CNC porting a head takes a job that may have taken weeks to do by hand in some cases, and turns it into just a few hours. Another huge advantage is it will also remove any flaws that the casting may have — like core shift — making it much easier to verify that every port is exactly the same,” states Shawn Hooper, Cylinder Head Instructor for SAM Tech.

We will try to give you some ideas on what to expect from the porting that Hughes Engines calls their CNC SUPER PREPPED HEADS, for small blocks, when applied to the popular Edelbrock aluminum heads.

Arrington Phase 6 CNC Ported Heads for 2011 and up 392 (6.4L) SRT8 Chargers, Challengers and 300Cs are now available. These upgraded 392 heads include improved valve springs, retainers and locators and allow support of cams with up to .645” of lift. The valve seats are single point CNC cut So far we have learned the following: The bad CNC heads intake flows on average from 0.050″ to 0.500″ 1.7% more than stock.

Myth #5. Because It’s Ported, It’s Good For My Application Here is a gigantic misconception.

So far we have learned the following: The bad CNC heads intake flows on average from 0.050″ to 0.500″ 1.7% more than stock. The stock heads exhaust flows on average from 0.050″ to 0.550″ 0.285% more than the CNC head! The stock heads exhaust flows on average from 0.100″ to 0.400″ 6.08% more than the CNC head!

The port on the left matches the Fel Pro 1289 Fast Burn gasket. This is our “Super Model” port ( because it’s tall and skinny).

The traditional method of modifying cylinder heads by hand fettling was superseded some years ago with the advent of CNC (Computer Numerically Controlled) machinery and CAD-CAM (Computer Aided Design – Computer Aided Manufacture) techniques. HD factory ported heads I've already pulled the heads and you may be right it might not be the heads but something is causing abnormal combustion.

I was lucky got to pull all my engine stuff off and will repeat the build on my new bike with a little less compression this time I think As for the CNC ported heads they worked well.for me depends what you want if your chasing low down torque just use the stock heads I flowed mine before buying the CNC ported heads the port shape and size wasn't the restriction the valve size was.
