Gas Flowed heads.

As mentioned in an earlier post ive decided to get my heads gas flowed.
has anybody done this and can they tell me about the difference in performance.
Im gunna wait on the new Velocity stacks, motobox spacer and completely remove my secondarys and shafts before i get them done.
This with all my other mods already done can then all be set up together and then hopefully i can just ride the shit owt of it LOL

There is a guy on here doing this as we speak. He should be posting up some numbers pretty soon. If you do it think about having your cams worked and bumping compression a litte to take advantage of it all. Then get a really good tune because there is no maps for this through Tuneecu as of right now. Good luck and shoot the numbers when your done as the heads on these thing leave plenty of room for improment!
