Cams aren't too bad to install, but have fun now that you've lost that torque advantage...

It's just conjecture at this point, but a few tuners have said that both the intake and exhaust ports look small on the Sky 2.0. They've still got a few things to try before going to the machine shop, they're talking about doing flow tests on the head and larger throttle bodies.
