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?

Just a little back round on my plans so; we don't get the waste of money conversation rolling on using original casting heads...
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!

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. 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 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 ... 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.

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