Advancing the intake cam increases overlap. You normally have the most overlap at peak VE and then it tapers from there depending on how well the engine/ setup flows. I would not advise using these cam angles for partial throttle driving too. You would more than likely loose torque. Partial throttle would use less overlap, how much? I'm not sure. It's very hard to tune partial throttle torque with VCT, IMO.
