It'll hurt your top end, but I'll do my best to explain it to you anyway.

1.) Get the durations of the intake and exhaust cams at .050 lift.
2.) Derive the overlap amount by comparing when the intake valve(s) close versus when the exhaust valve(s) open.
3.) Adjust cam gears accordingly.

I can't guarantee that this is a safe way to tune your car, but just out of curiosity, why would you (personally) want to do this?
