Let me start by saying I have a pretty nasty knock on my z6 head so I know I need to adjust my valves but I also need new piston rings so I'm take of the head and this is where my question is can I adjust the valves with the head of or do I have to do it with the head on if somebody can help me or give me a clue. Also if I somebody can give me the gap number
