Re: VTEC (not really), and DOHC

i dont think SOHC can have 4 valves per cylinder.

Examples proving otherwise
99 Chevy Metro 1.3 SOHC 16 valves
95 Chevy Lumina 3.1 SOHC 24 valves
87 Porsche 944S 2.5 SOHC 16 valves
95 Dodge Neon 2.0 SOHC 16 valves
94 Mercury Sable 3.0 SOHC 24 valves

DOHC heads are more efficient cause they don't use long rocker arms to control the other set of valves. Less rotating mass = more HP. Most DOHC engines hydraulic lifters that directly engage the valve. IIRC
