Hello nice people. My son has a 1988 crx Si which he is trying to make faster. He has a friend who has a head that supposedly will work for this "mini me" swap. I can tell that this head is V-tech however how can I tell exactly what head it is or what it may have come off of? Furthermore I have no clue what to do with this procedure, does anyone have any info that can help? Please if your just going to insult my lack of Honda knowledge please save it, positive feedback only please.. Thank you people.
