to set the record straight the L series engines are only a few years old.
they come in 1.2, 1.3 and 1.5 liter models.
the 1.2 and 1.3 liter models use a different head, which utilizes two spark plugs per chamber, each firing at a different time during combustion to allow for a more complete burn.
the reason the L15 uses a vtec head instead is to increase the performance to be competitive with other models, especially in the US market, where performance and torque is key.
