But it has a 16-valve DOHC head, not so restricted as the 8-valve pushrod used in the Cummins. Anyway, if Cummins managed to get 4 valves per cylinder in the ISB-series while still retaining the pushrod layout, why not to apply it into the ISF series? I still consider it better for commercial purposes, as many commercial operators still do...
