Someone did a set of Pro Comps that imo will blow the eddy head out the water.
Material ( aluminum ) was even better with more meat to take out.
I heard results from just a procomp cnc head that impressed me.... In other words, with just the procomp " factory" cnc job.
Uh on, now you're going to get the haters in here...DUCK!!
Back on point: Where would I find such data?? I'd really be interested to see #'s from flow testing that head.

Can you post the CNC flow number from the ProComp CNC head?

It's not a secret or anything.... Lol.
A member here in a full weight bench seat A body went 10.50's at Quaker( which would be 10.30's anywhere else) with a 9.5 to 1 compression 4 inch motor.
I found that extremely impressive for a first outing.
If I remember the heads peaked at 288 ish intake. Don't know any other numbers.

Some Indy 360-2 oval ports, have both exhaust patterns on them. Brett Miller on here did the set of pro comps that went 10.50s. He has a cnc program for them now. If you go w9 route he has a cnc program for them also. I have been 9.40s on motor and 8.57@162 on spray with his w9 heads.

No the set I am talking about are only cnc'ed by pro comp. the set you are talking about Brett doing haven't been used yet. Those are going on a higher compression, more max effort motor.

And those numbers "blow the Eddy's out of the water"??? 
I know flow benches are different but my hand ported Eddy's flowed 265 at .550. My cam is only a .520 lift so I wasn't interested in higher lift numbes.

Hi Ian.....
My understanding is the motor is in a Dart that is all steel except the hood, with bench seat.
60 over 340 block 1/2 filled, small roller, 4 inch crank, and cnc pro comp heads. Compression is 9.5 to 1. Quaker is about 2 tents slower than other tracks, so , IMO, running 10.30's at a "normal" track with no compression and not having a light car is real impressive.
The heads used don't have the pushrods moved over, just a cnc on a "stock" pro comp head. Maybe someone did that cnc other than pro comp, I don't know/ forgot to ask....But I do know these aren't the " trick" head Brett is working his magic on. That set of heads hasn't been put on a motor yet.

I was just trying to see whats out there.My current combo runs ok for what it is.I have to make a call on a torque converter and just deciding to change the motor or leave it as is and work with it.I have flowed my heads and they were 268 cfm @ 600 lift.I ported these and they seem (for a home job) they work ok.My combo is a 410 10.5 to 1 (180psi)with a flat tappet solid cam.My car is 3150# w/driver.I have been 123.77 mph with this set up.My best et is 10.95 w/1.53 60 ft.How fast can a car go if it runs 122-123 mph in the quarter?This is pump gas w/mufflers.

Yep, at that weight it's very possible to knock a tenth out of that 60 foot. I went 1.44 with what I had, with about a point more compression but good bit more weight. My eddies went 274@ 600 stage two job Hensley did,.... Picking up 60 foot will really help the whole time slip

When my Barracuda was on pump gas it ran 10.79 @ 123 with a 1.49-1.47 60' time. This is with a 410, 10.8:1 comp, pump gas, small street roller, through the mufflers, 3250 lbs. You could make nice gains if you can pick up the 60' times about 5 hundredths. I would go to a TNT and try different pump cams and squirters on the carb to get the 60' times down.
For what its worth, my ported eddy's flow 293 @ .600...but my cam is only .550 ish lift. I switched to e85 and the car picked up a CHUNK of ET. Now its in the mid 10's, and should be in the 10.4x's this fall.

I believe that is because w2 headers had 2 different bolt patterns if I remember correctly if you hold up a standard exhaust gasket the ports don't line up.
but its been a while since I was playing with w2s

I believe you are right
It will work ok on a bracket car with cheap gaskets and red high temp rtv
I wouldnt do it on a street car.

Stock header bolt location yes...But far from a stock exhaust port.
J,X or eddie, and pro comp is a stock exhaust port.I wish i could post pictures.
I'm agreeing with you. If he has to retain stock exh. Flange
I would not use the Indy heads
I don't know which would be best. I've seen several cars run great with the eddies

Who makes those gaskets with the dual bolt pattern? That set looks like they will work for me. I have econo W2's on my 408 in my d100. So no one makes a W2 header for that combo and I have to use standard headers. Always have trouble with them leaking.

I have been really wondering where I will go next with my motor and this has been a good discussion thanks. I have Shady Dell stage II Edelbrocks with 2.05 intakes. My car has run a best of 11.18@120.5 364CID 3525lbs full exhaust system. I have a 4" crank and 340 block I have talked about putting together for years. Now my next project is EFI instead of that(hang on little 360 lol). I keep wondering if the next step should just be Gen III.

My eddies were ported by Dr J. They flow a tad over 300 @ 600. They took my 410 with 11.8 compression and E85 to 10.53@125.6 full exhaust and factory hydraulic roller set up with a race weight of 3500 lbs. Dynoed 583 on a 850/ 596 on a dominator. I'd like to know if anyone is running hughes big mouth heads? They do have a offset intake, but factory exhaust ports. His website makes some pretty impressive claims.
10.56 at 125.6, with a 1.43 60 ft.

Who makes those gaskets with the dual bolt pattern? That set looks like they will work for me. I have econo W2's on my 408 in my d100. So no one makes a W2 header for that combo and I have to use standard headers. Always have trouble with them leaking.
If you are talking about the ones I posted, they are tti, and I bought them from Hughes engines

Edelbrock claims a 58cc combustion chamber, not so...it's more like 63cc
My heads were cut .030 and ended up at 57.9

I thought the 58cc was for the magnum head and the standard was 63?

These are some CNC ported Hughes magnum Edelbrocks w/ 2.08 / 1.60 valves. Per Hughes, intakes flow 304 @ .650 and exhausts flow 223 @ .650. I measured the chambers @ 63 CC's. Probably were around 60 before the CNC work.
