My B20 non vtec head has 33/28 mm valves from Honda as a B16a head, and the intake port is more direct and bigger than a B16a The limit of the head is on the lift of the cams and nobody has aftermaket valves on it9400RPMS wrote:Not really Vtec heads, valves, ports and everything flow differently from a "non" vtec head.thething96 wrote:It shouldn't matter if the engine is vtec or not to hit that 220whp mark. The main difference between is vtec=low cam lobe and high cam lobe, non-vtec= high cam lobe only. If both setups flow similar, have similar mods,cam lift and duration is similar,both should make the same power, right?
one other header you should consider is from bismoto. if you contact them and give them the info about your setup they can custom make a nice header for you. their stuff works really well. http://honda-tech.com/showthread.php?t=2660137

Most cases what you're saying is true, but with good resources, all motors non-vtec can and will make more power that vtecs. Just look at Bisi, with his single cam, non-vtec, all motor Insight. Granted some of us wouldn't have that much income, time, and knowledge to do the same, but it can be done......My B20 non vtec head has 33/28 mm valves from Honda as a B16a head, and the intake port is more direct and bigger than a B16a
