I had one for week to do a show with and they look awesome. Jeff at Modern Cylinder Head does the CNC work.

Does anyone know if the CNC is with the stock intake port size or has it been enlarged to the max wedge port. I want to run them with a six pack intake manifold.

Here is a picture of the CNC Stealth head next to a stock head. The CNC port work looks very nice in the Stealth heads.

Is that why they are called "Stealth"?
paint them to match the engine and they will look like stock heads... freeze plug, etc.

Anyone have any good pictures of the CNC heads chambers? I want to run a set on a 383 and I am concerned about the compression.

Here are the chambers. Typical closed chamber, looks a bit like a 915 head.

For a head that is a dead ringer for a stock head 320 CFM is very respectable if not unheard of! Kudus to Jeff for working his majic once again and congrats to Brandon in his decision to use MCH.

That's an awesome price for a CNC ported head that flows that good. I would jump all over that if starting from scratch. They're probably very similar to my old Eddy heads that ran 9's on a streetable combo, great deal.

They should be. As far as I've understood, the CNC program is just the same as used in RPM heads.

At this point I would not bother to listen to any thing wedgeOmatic has to say when it comes to 440source, He has posted in the all 440source threads about his valve cover problem many times over and over

How about some pix of your car??? Sounds like a real nice combo you have... I am planning on using the stealth ported heads on my 500 sixpack and want to look stock but carry a big stick! TBF

Maybe we could trade him for Eddie? At least his ranting and raving had some entertainment value.

Back on topic.

Well said!!! Getting very old seeing his continuous whining of 440 source parts. Give it up already, Wedgy!!!
