shit, sorry man!

they are worth it - but you gotta factor in paying some dude to tune them.

i had Jim at Croydon Racing tune my cam gears on my B20VTEC and it gained 11kw and had good midrange power...

he told me that every engine is slightly different, so what worked on mine wont really work on someone elses...

charged $350 for the tune.

do NOT try to set cam gears your self!

BTW - if your engine ius stock - you coudl still gain, but it it has intake and exhaust gains will be higher
