Hi, my friend has a 96 LS teggy, and wants a new head for it to make it vtec, I wanted to know for him what is everything he will need, for the wiring and what not, also is his ls engine long block or short block, I never did find out which was which. He either wants a gsr head or a b16 head, which do you suggest and so on, thanks for your help in advance, KYLE
