Start here with the cams you are thinking about including your stock cam.

On order to reach the numbers your looking for the dcr will need to be spot on for your type of fuel. You will find ypur stock cam had a conservative dcr for street driving. You will need to push the envelope a little further the rpms up higher and the push the compression up.

You will need to get the lift up i am assuming you have big valve heads. If not might as well get that sorted out now.

I will usally look for the max rpm my engine can take and then work on the compression ratio until i can support the desired rpms and still meet my other needs.
