Quote: Can you say airflow.after this I think a lot of people will say w9 are a good head. I have a new set in the box that I will get done that I paid $500 for them I could be wrong but I don't think you can find a new set of w8 for $500
I don't know that I have ever heard anyone say that the W9 is a bad head. They just never got much of a chance to prove themselves because there wasn't any real development work done on them. The only highly developed ones were the RP versions that were done for the Sprints and work well for those applications. I think as more people see how much potential there is in these heads that they will be pleasantly surprised. It is basically just a lighter W8 and new castings are available.
They took a W-7 and a W-8 and came up with a light weight W-9.... like you said I never heard anything bad on them... I like my W-9s(CNCd Chapmans), this winter I'll put a cam in mine so its more in line to what it needs... I'll see if they can re-grind my current one or I might have to send my spare blank in to get cut
