spark plug gap

[87gt17815]

depending on your fuel pressure and how tuned the motor is you can probobly run a bigger gap the that. Although not all cars are the same. If you think you picked up power then leave them alone. But on an almost stock motor tuning with spark plug gap is not all about power because it will be minimal, it getting your motor to run as clean as possible and efficient as possible, hence more throttle response and power across the rpm range.
