ZZ-9 cam in stock headed LT1

Any one ever do this swap, and what kind of numbers did you come up with. The way the cam favors the exhaust side, it looks like it would work really well with stock heads. Specs are as follows: 212 226 dur @.050, and .483/.520 lift with 1.5 rockers, .515/.554 with 1.6. Lobe seperation is 112. Thanks, Prorac1

The ZZ9 is just slightly more aggresive than the Hott cam, so your performance will be on par with it. As a note also use the 1.6 rockers with it.
