For one i think its more money and trouble than its worth. plus it will never fit or work as well as the original honda engineered engine. your putting a block made for midrange power with a head made for high range. if you want more displacement just get it out of the gsr block. i was just reading something on team-integra written by their guru over there, micheal delaney. he had some well researched opinions on it.
here is a good thread on it

with the amount of money it would cost to do the lsvtec i would rather turbo the ls, buy a gsr, or even all motor the ls motor
the results dont outweigh the cost, effort, and potential problems
