I'd like to know what's the best head for a Turbo LS/VTEC??? Should I go with Si-R, GS-R, Type-R, etc
And plz explain why.....From now on, I've been told to put a Si-R head, but I wanted be sure before doing something.....I'd like to understand what each of these heads do to make my choice regarding my needs. Thx a lot for your help
