I know everyone is probably tired of this but.....
I have a friend with a 93 si 4ws and i need to find out every possible thing there is to know about swapping a vtec head onto his motor like: what year head works best? are there any differences in a h22a1 and a h22a4 head? what problems do you run into? how do you fix them? does anyone have a head for sale? does the head just bolt on with no problem? does the intake bolt on with no problem? would a piggyback system like apexi v-afc work for the vtec function? if anyone can point me in the right direction like a website or a detailed article or some crap like that i would greatly appreciate it. thank you for your time.
does the head just bolt on with no problem?
