It's a custom grind by Ed Curtis of FlowTech Induction 224/228 600/600 114 +4...very stealthy as I asked.

Those specs tell you how well he matched the cam to the flow capabilities of the heads. To my thinking, the balance between the duration and lift combined with the 144 lobe centers for high flowing heads is very well done, but I guess the dyno numbers show it. The valve springs were changed at some point, right?
