when i was ajusting my timeing i put it at *12 without the spout in and when i connect it the timing jumps to 24* is this right? also how do i know when ive added too much timeing because when its at 14* spout out and 28* spout in and it seems to run slower but i dont hear my car ping at all could it be that i have a header leak? my headers are leaking because i think i blew the gaskets on my bbk headers because there both leaking i need to replace them but how important is it can i wait and my car be fine?
