well. My friend wants to know how to identify a VTEC head w/o havin to look if it's a EX,SI, or for the vtec sylinoid. But anyways, we got to the part of how the spark plugs go in the front of the valve cover(or towad the front bumper) and that's what all VTEC(z6, y8) have. and LX, DX have the spark plugs located in the back of the valve cover. and when ppl say that on here, some ppl come in with 'that doesn't mean anything'. So how does that not mean anything, I haven't seen the spark plugs in the back of the valve cover on a VTEC head, or vice-versa. anyone?
