that's one of dem fancy 12 valve 4 banger heads.


I think the early (1985) honda 1.5 liter engines had just 12 valves. It was a SOHC

Siamesed of one of the other ports with the valve timing adjusted on the 3rd valve to aid either performance or emmissions.

Isn't that the whole VTEC concept. At a certain RPM the 3rd valve would open?
