That line is 4.180 and you may not run this on a 4.180 bore.
This can be done by hand to run on large bore but makes head "fit" more Applications.

Not to mention not all bores are the same place in the block. This way if you have a block with some core shift you can move the bore around a little and then match the chamber to it.

Re: w9 cnc heads - 12/22/11 05:40 AM

Make sense, sounds good.

When I was putting my 472 together, during the mock up I put the heads on and then scribe the head to the block. This takes care of the core shift problems.

Just my

Keep us posted on the build, looking good!!

any new news on this program? any flow numbers? what do you think about the w9 heads?

Posted By: W5DART66

Re: w9 cnc heads - 01/25/12 01:55 AM

Flow on the intake port should be close to this as its getting same intake port as the W8 I did. I hope to have 2 sets of the W9s done next week

flow #s
0.4000 276.3
0.4500 303.2
0.5000 328.6
0.5500 350.4
0.6000 367.5
0.6500 377.6
0.7000 382.3
0.7500 389.4
0.8000 394.3
0.8500 399.0
0.9000 402.8
This is at 28" of water port is nice and smooth.

are they paper thin at that size? it's about time for me to start working on my w 9 engine again . it will be boosted so I'm not sure that will need them large though lol

Not that thin but whats nice about having program on file for this head now is we can do just what you are saying. I can add .020" to the entire intake program.

How does your w9 compare to your w8 flow numbers specs?

Posted By: W5DART66

Re: w9 cnc heads - 01/25/12 03:07 PM

Its same intake port as the W9 and now has better chamber but I have not flowed them yet as I am getting first 2 sets of the W9 program done next week (I HOPE)

The chamber in the W8 was just the chapman/mopar with little work.

Re: w9 cnc heads - 01/26/12 01:54 PM

So what does it take to do a swap from say like a Indy 360-2 head to a W-9? Can they even be run on a 59* block? Don't know much about these heads except they flow great! Just looking for some education. Heads look great!

Re: w9 cnc heads - 02/02/12 05:38 PM

Can I use the 59 deg W/9's with a 4.08-4.100 bore?I'm wanting to use these on a 70 360 casting I have,and IF possible avoid going to an R-3 for now.
Another thing is,does anyone out there know of anybody that can make headers for this beast in a Duster?Again,IF it's possible,keep the t-bars.

Re: w9 cnc heads - 02/10/12 04:32 PM

My CFE w8's had a sleeve where the head stud area was broken through. They also used a 7/16 head stud instead of the 1/2". Was told the sleeve was to strengthen the head so the head stud when torqued down would not crack the head. Probaly less chance of cracking the head with the less torque the 7/16 bolts require to stretch the stud.

Re: w9 cnc heads - 02/10/12 05:35 PM

I would put a sleeve in it just for the crush reason. I have done it on other heads and it works good.

Re: w9 cnc heads - 02/10/12 05:37 PM

The heads look real good and I'm intesested in having a set of W9's done.

Do you have any idea what the CnC charge will be?

This is the #s right now(Right out of CNC) .Valve job no blend into chamber/light blend into bowl.
Lower lift/mid lift numbers will get better hate to put the numbers up but don't know when I will have time this week to do rest of the blend work and get them back on the flow bench.
The port takes off .600" up and the sound is sweet.

Re: w9 cnc heads - 02/15/12 04:25 AM

700 lift and above the W9s are better than the 8s.i guess i cant go wrong with the new 9s i bought new for $600 shipped,bare of course

Re: w9 cnc heads - 02/15/12 07:26 AM

Man that is real good!

Do ever work on Big Blocks?

I just bought a set of W9's and with those kind of numbers you could make some serious power. I was going to build a 440 small block, I might have to rethink that and go a bit bigger.

I would really like to get those kind of number out of a set of B1-BS heads.

Posted By: Otherlane

Re: w9 cnc heads - 02/15/12 01:27 PM

So a w8 and 9 should be pretty much close on power with the flow numbers on the 9s?

Posted By: W5DART66

Re: w9 cnc heads - 02/15/12 01:50 PM

I dont see any reason it should not.
Most of the W9s that are CNC were Dirt track stuff not the best ports or chamber for GAS drag car.
This set up is for drag car/fast street car. The W9 is much nicer than I thought going into this deal vs W8 early castings.
The W9 is light but it has Material in the right spots for nice intake and exhaust ports. We did pressure check this set of heads at 100psi no leaks.

Re: w9 cnc heads - 02/16/12 03:01 AM

Its about same price but seats and guides add $$$$$ fast.

B1-BS head doesn't have a tall enough port for that kind of flow. Only so much you can do with a standard port height. Better capability with the Victor head or the Indy EZ due to the raised port.
It would be nice though, standard height intake port and that kind of flow? It'd surprise the crap out of folks.

Re: w9 cnc heads - 02/16/12 06:37 PM

J,

If you had any tallent we could get 380 out of a set of B1-BS's.

Is that 440 block a 59* lifter bank angle block? I ask b/c I have a set of fully ported W9's for my R1 block but the 59* block with it's 1.875 lifter bore spacing makes me nervous with the push rod angle.. I know I can run the offset rocker but the little 5/16 push rods is less than desirable for my boosted application.

Posted By: Biginchmopar

Re: w9 cnc heads - 02/20/12 06:54 AM

Sorry, R3 48*!

I don't want to fight the bad lifterbore angle. My buddies at T&D have shown me how important it is to have a good Valve Train.

How you think the 9s compare to the 8s that you have worked on? just asking because there is always a talk about which will make more power and w9 cant make big power.

So far I think W9s have not been given fare shake I think they will make good power but most of the W9 stuff was for dirt track ports and chamber all wrong.
I did not like the W9 for same reason but now that I have worked with them they are nice, Intake port has more meat in it than early W8s.
Draw back is the valve are .100" closer to exhaust side of head.(this will hurt small bore more and small bore with big lift .750"plus will be at disadvantage)
I think if you are doing W9 engine you should run 4.150 bore or bigger then valve placement would be a wash.
The other thing I am updating 3 sets of W8s right now and they are all a PITA start with new W9s and dont look back.
I think my W9 in max effort NA deal can do 850~900HP to be seen but the data on the head backs this up now just need some one to step up and build one.

Re: w9 cnc heads - 02/28/12 08:44 PM

Stupid question:

Does your program take a regular port W9 and raise it to where an as cast W9 RP head is OOTB, or are are the castings completely different? I guess what I am asking is will your program working in an older W9 and a W9 RP just the same?

Re: w9 cnc heads - 02/29/12 02:50 AM

Shoot me a pm $ on just the chambers only,
Mine is going to be more turbo street than all out race... And beside NRE gets 1500hp out of heads that flow about 300 cfm when boosted & I'm not sure if efi engines suffer from large ports on the street like a carb'ed engine @ low rpms.

I usually go for the overkill side of everything ( And usually wind up with a mess)God they look sweet though

Re: w9 cnc heads - 02/29/12 05:21 AM

W9 chamber is 61cc with SS valves should be about 58cc with flat Ti valves.
Intake port is 303cc with SS valves Ti valve should be 298~300 cc
