I just noticed those in my HotRod magazine, but forgot to check them out later. Until you posted this message.

I didn't find any detailed flow numbers, but did find a few pics. Can't believe Dart doesn't even show the chambers on their website, if they do I missed them.






The guy from Dart in this video, stated they were made in the USA.

Here some numbers for comparison. I don't remember where I got the numbers for the Dart Pro1, but I did have this chart that I got them from. The numbers for the Brodix IK200 come from the Brodix website.

don,t think flow numbers are everything there is to know about making good hp, theres several other factors that have a good deal to do with the results, Ive used those BRODIX heads frequently on 383 builds and they are excellent heads, a very common mistake is in selecting heads that are either too restrictive too allow your horsepower goal to be reached or heads with larger ports and great flow numbers at high lift, than the combo requires, but then matched to a cam duration and lift and gearing that can never use the max potential flow rates
