This question has probably been covered before but im new to this site. I have a 92 prelude si with an h23a1 engine and would like to vtec it. does anyone know if it matters what year range h22 head to use? i found a h22 vtec head from a 98 prelude. I guess what im asking is...can i use a 98 h22vtec head on my 92 h23 block and run it with the obd1 electrical components?
