You have never even taken either apart so your talking again out of your virgin ***. Vtec heads the dohc form are so popular for a reason out of the box they had bad ****'s. The rocker assembly is bulletproof and can handle whatever you throw at it.
Conclusion ls heads are cool and nothing wrong with them but the vtec head is the hot blonde in the class the ls head is the kinda chubbby cute girl.

Re: thoughts on vtec
in my expereince if you are messing with single cam engines and your car came non vtec then leave it alone. i had a crx si with the a6 and spun a bearing after a year or so. then i got a z6 and it felt the same as the a6. if you drive a single cam vtec car and vtec doesnt work, then it sucks ***, but when it works there is no surge of power at all like in a b series, it is a smooth transition.
going vtec with a b series is worth it for the reasons chris stated. in stock form they are a lot better flowing and can rev higher. to me this goes back to if your car came with vtec then i would use a vtec head cause its all ready to go, but if i was swapping b series into a non vtec car then i probably wouldnt worry about it unless i was going for big numbers
