I just picked up my CNC'd 906 heads from K&G Engines last night. After speaking with the owner (Dave) over the years, I'd go home and searched Moparts to see if I could find info on the company and did not find much. More recently, I've seen some posts with praise for the company but, no pictures or anything. I've never heard anything but positive remarks in any conversations that I've had with people that have dealt with the company so; I pulled the trigger.

I figured I'd post some pics up.

Just a little back round on my plans so; we don't get the waste of money conversation rolling on using original casting heads. I plan on running my car in the FAST class at some point so; I will be required to run the 906's.

Dave was great to deal with; I have no complaints but, the SLA for completion did run over what I was originally told but, I understand as this is not a huge operation.

My camera is not the best so; these are about as good as it gets.

Is that a breakthrough that has to be epoxied? I had to do the same on my 915's.

Heads look very nice.

I agree...your camera stinks.

Flow numbers?

I've heard "290-ish" thrown around from those heads.

Are the intake port openings pretty close in size to a valley pan gasket?

Those pics are real proof of the CNC program for cast iron heads. I'd have to assume that the machining has to be done with some stealth because of the cast iron castings. Better to bring life to some old iron than to have it come back as some steel s!*t from china. If you don't mind,can you just let us know if the completed product was cheaper than buying new aluminum heads and having them ported in a similar manner?

Understood. My concern is cost of replacement if these 906s crack (not uncommon) and you have to start from scratch with another set.

The spots that can be seen in the some of the pictures are simply imperfections in the casting; no break throughs or epoxy.

I’ve not placed the valley pan gasket up to the ports yet to see the difference between the two openings. For everyone’s information, this is his original program (although he has made tweaks to the program along the way). He has another program that he has written however; it is more aggressive and you must run a valley plate with that deal so; it would not be approved for FAST.

I do not have a flow sheet but, he claims 290-ish. His newer program I believe is claimed to be around 320-ish. I plan on driving this thing a lot too so; I did not want anything too aggressive and be overly concerned with cracks although, I know they can still happen.

I paid $1500 plus tax. That includes the CNC port job, new Ferrea 2.14 1.81 valves, new seats, guides, retainers, springs and ext. He has programs for other cast iron heads too; he had a 516 on the CNC machine when I was there. He had 10 sets of 516’s to do that customers sent in. My 906 heads were part of a batch of 20 that customers sent in (with numbers like these, I’m shocked that no-one has posted pictures).

I plan on working on the car this weekend- painting parts, disassembling things, cleaning, maybe re-assembling partially or all the way. I’d like to make it to the track this year but, I’m not going to push it.

It might go back to the chassis dyno too.

Eventually, I’ll let everyone know the outcome.

Brad, if or when these crack; I'll throw a set of Stealth heads on it and be done. This car will not be cut up or caged and I want it to appear stock. As we all know, things can break and we can loose money; that's kind of par for the course.

Looks real nice and glad to see you're gonna put em to use. I like the idea of porting stock heads for some reason, even though we all know it isn't generally cost effective.
Looking forward to hearing how it runs!

Sounds like my days of porting 906's are over!!

That's super cheap.

I wonder how long it takes the cnc machine to port a 906 like that.

I'd like to see a flow sheet on a bench I trust before going out on that limb ... wink

Have you had a set of these yet ? I wonder what a hand clean up after the fact would do to them ?

Even if they flowed 275-280...... That's still really cheap money.

Similarly equipped heads out of my shop....... new guides, ex seats, big valves, all new hardware, etc..... For $1500, you'd get a nice bowl blend, intake port gasket matched, some intake short turn work...... They'd flow around 260-ish.

As I mentioned in another thread......... It's pretty hard to compete "head to head" with a cnc machine when it comes to porting.
If someone has a program for the heads you want ported...... More than likely it will be less expensive to have them done that way.

As more and more shops buy cnc machines, it seems as though the prices for some of the more basic porting jobs have dropped a bit in price....... As the shops "compete" for the customer base.

Yep. I have one more set of cast iron heads in me and they are my w2 heads. No more iron. I may call them and see if the have something for w2 heads. If not, maybe I can do a port and they can digitize it.

Another thing is, it sounds like they had some 30+ sets of bb Mopar iron heads to be done..... Which means they could buy all the valves, springs, retainers, etc. one time..... Which presents an opportunity to buy those parts at a better price..... Which helps with the bottom line.
As well as sort of an "assembly line" type of situation for doing the guide and seat work on multiple sets of heads with only one set up.

Obviously, if they have 30+ sets of BB Mopar iron heads there to be cnc'd, they've found a price point that's pretty attractive.

Someone needs to port the prototype, write the program, do the VJ... CNC porting is only as good as the program/port it produces

Answers to some questions above

My car is a 69 Road Runner. The car scaled at 346X pounds without my 215lbs. It has a low deck 470. The rotating assembly is from 440 source. I’m currently running a Comp XE 274 cam which is .488/.491 lift and 230/236 duration at .50. Performer RPM intake, 850 Street HP, stock manifolds, 2.5” TTI exhaust, some pocket ported 213 heads with the same size valves as the new head (I bought the old ones from Hughes) and an 8 ¾ with a 3.73 gear. If the cc of the head chamber that is on the car right now is what I was told, (I take what I was told with a grain of salt) my current compression ratio is 9.65:1.

Before a few years ago, I had Hooker Comp long tubes with a compression bent 2.5” exhaust with Flowmasters. My best run with combo was 12.25 with Mickey Thompson Sportsman Pro Radials.

Last year, I went to the track once and got one clean pass and managed a 12.48 with the manifolds and new exhaust. I really think some 12.30’s would be easily obtainable; the track was just not there that day. The 12.48 run was the first pass of the day and I short shifted on the run (I was trying different things that day given the new exhaust set up).

Dwayne, Dave said one 516 takes 5 hours to cut on his CNC machine.

He also has CNC programs for aluminum heads; I just don’t know how many heads he has programs for.

Cool thing about the CNC is you can be doing other things to make money while it's carving away on a head.
