Many factors come into play in regards to making the most out of any combo, and some are listed in post 28.
Another factor to consider in regards to street performance is in the compression ratio used.
The smaller the chamber the more vacuum the motor will have and that goes a long way to helping out with idle and tuning for the Cam being run.
If you not looking to get passed the 415 hp level with stock heads then I would not choose to run more then a 9.5 to 1 compression with the amount of CID your looking into running .
