Just a note..The term "ported" gets thrown around a lot..there are a bunch of ways to "port" a set of heads. The right actions make for good power gains, with no loss in low end. Some other ways to sacrifice a little low end, but get better gains at higher rpms..And there are still other ways that look really good, but sacrifice low end, and cant deliver high end either. Be sure your shop can do a nice job.
