yeah me too Just want to go a little bigger when I pull the head to install the HD springs and new valve's & seals still not sure when or if I'll ever do it now that it's riding season just getting annoyed by the valve chatter
The 252x1 is a .450 lift, most consider it a full race cam. Its a really good cam if your in the mid to high rpms most of the time. That being said thats what I have in mine, you can tell when you hit the range the cam likes!!!
As far as high rpm cam it's not torque then hp in the rev range. The 1905 wb I have is a true high rpm screamer cam. Still a nice cam a a good deal on the entire setup. Is this head ported?
