Is anybody running WCCH heads right now?
Anyone have any drag times or dyno numbers from these? Or are we still waiting on the many who have purchased to install theirs? 
Some folks out there are thinking about heads and need to know...

Give me a few weeks and maybe I can help you. Do you need flow numbers? I am sure Richard will chime in here, he is on here from time to time.
I went with them cause of their flow numbers matched my cam and I could stay at the stock compression of the LQ9. The chambers on the Dart head are 62cc, which are way small for me I would be way over 11.1:1 with that head
Who has any tech specs on the new Dart head? I don't think anyone has had them dynoed yet either.I have seen some flow numbers from the "as cast version". I don't think there even is a CNC version done yet. Now I know they are going to change the valve stem size to 5/16 from 11/32. Dart makes a great product, but I don't think they are proven yet either.

Now, even with smaller valves you are going to lose some port velocity. How much is the Big unknown...Now they could have some smaller port size that's not advertised on their site. I have not spoken with them so, I don't have any experience with their product or line(to make an educated guess), maybe they could chime in on one of these post....If they are all 235CC heads though, I would look to 225CC AFR head before going that big....OK, actually I would buy a 205 port. That would work the best on smaller cyl engines...
