I'm looking for flow numbers for the 180 and 200 Pro 1 Platinum heads, their web site seems to only have flow numbers for .500 lift?

That's because the valve don't open much more than that on the small heads

I don"t think dart makes the 180 pro 1 in platinum.

From what I understand the pro 1's are all platinum design. The dart iron eagle 180 is not the platinum design.

When dart was going through the development process for the platinum heads, they found that the 180s were already really good in their wet flowing testing and as such did not need modifications like the rest of the line.

nice heads.... I am hoping to get mine dyno'd as soon as the weather warms up a little.

The heads reach max flow at .500 So additional lift only has the same CFM. All heads reach a max cfm at some lift point.

Hi just finished bulding a 383 using Iron eagle platum 200cc heads took them to local race shop and had a good port job on them with 2.08 1.60 valves at 600 lift the flowed 305 intake and 217 ex. The guy that ported the heads said they were one of best heads to work with he has flowed some of these heads that went over 323 on the intake side at two horse power per cmf these heads make tons of power. Just bump the the gas and the set you back in the seat. I,m running JE pistons, and Comp Cam full roller cam 9-990-9, Intake is SUPER VICTOR 2925, hooker super comp headers, hp Holly 1000 carb. I also have a cheater nos plate system with 250hp hit. MSD 6 digital box light the fire. This car stall at 3200 and flys to 7000 between shifts eats stock sprot cars for lunch no doubt best bang for your buck is platnum heads.

I didn't get a chance to flow them, but we just used a set of 200's on a Dart SHP 400" pump gas motor and made 554HP/520 lb ft with them using a 750 Holley.

According to a couple of different sites, max flow is listed, in fact .700". Dart only listed the .500" flow number for the 180s.

One thing I found important is that the flow didn't go DOWN at the higher valve lifts as some heads experience.

Hi done some more work to the 383 I had full port put on my 2925 and picked up a bunch of time and power. I got a chance to run my camaro at A good stick track. I ran a 10.88 @ 122 in a 3500 lb car on motor, the sixty foot time was a 1.2 .
My best time was 9.70 @ 136.8 with 180 shot of nitrous.
The 1/8 mile time was 6.1 @ 110 mph. I will post a video of my last run when I get time.

Nice maybe low nines with the 250 shot.
