No two custom grind cams numbers will be the same, that would be just blatant copying. I doubt if a hair more lift or duration will make a huge difference by the "seat of the pants" dyno.
You have to be 100% honest with yourself on the primary use of the engine/car.
Street? Street with the odd AX? Full race?
Even with street... is it city street or country street? Big difference.
No such thing as a perfect cam, you will have to make a compromise. You lose HP for driveability...you lose driveability ( and idle) for HP.
If you are not 100% honest with yourself about how you will drive your car, then most likely you will be disappointed with your cam choice.

Not putting miles on your car is like not having sex with your girlfriend, so she'll be more desirable to her next boyfriend.
