I need a set of Stealth heads ported, Hughes no longer does CNC porting, i wished Dwayne Porter could do them but he as well no longer offers the service, however he was kind enough to recommend me to KG engines, which i have been trying to get a hold for the last few months without any answer or replys from them.

Anyone know of a machine shop who offers CNC porting aside from the 3 mentioned?

thanks in advance

All the cnc head porters are backed up. That being said contact Scott Brown at buyracingparts.com. He has some great programs for Mopar heads.

440 source has them in stock.

I think he uses Modern to do his stuff, or at least he used to.

Interesting.

I wonder if they got their issues worked out with Modern?

Last I heard, they were asking around for someone to go try to get their pallet of heads back.

I'd probably try KG if I were in the market.

My impression is that 440 Source has someone other than Modern doing the cnc work now.

I suspect a phone call would clarify that.

Also, in the recent overview on a cnc Stealth head by Eric Weingartner where you could see the chamber side of the head, the chamber wasn’t ported like when Modern did them, and it looked to me like the same valve job that comes on the unported heads.

X2 On Scott Brown, He will do a great job , but you have to remember the current state of supply is horrible. You may have to wait no matter who you use....as businesses are short not only on the supplies and materials they use, but it is getting harder to get quality workers...

Like I said above, Scott doesn’t do porting, he sends it out. He used to use Modern to do the porting work he sold. Not sure currently who he uses, might still be Modern.

That's definitely not the same level of CNC and seat & valve work that the Stealths used to get from Modern. I didn't watch the entire vid to get the rest of EW's review.

I really like Eric's Youtube channel. Very interesting stuff.

It would be nice if he figured out how to pronounce the brand of his own flow bench correctly. It's spelled S-a-e-n-z... pronounced "Sigh-enz" (it's a Spanish surname)... and he keeps calling it "San-yez."

He's an Okie so he gets a pass.

If one of the new version cnc’d Stealths finds its way to my shop I’ll take some measurements to compare to the MCH cnc’d Stealth I checked out a few years ago.

My “expectation” is that I’d see a higher flow number on my bench than Eric saw on his.
I think it was 286@.800” on his bench, which seems pretty soft for a fully ported head.

Chad Speier mispronounces it the same as Eric W. Chad is from Kansas... what's his excuse?

Maybe they're related?

I have access to a new haas 4 axis machine . Will that cnc heads or does it have to be 5 axis

Not sure about 4 or 5 axis needed, but the other issue is a good program for the 440 source heads

Some people think you just bolt a head down and flip the power on. Instant cnc’d head. Good luck with that.

It's not going to be able to access the entire port without the 5th axis.
