I have a couple questions
1)Are the nipples (tubes) used as a guide for the drill bit? Is that what that's for?
2) can this be done with the head still on the engine or does it need to be removed?
3) can you put me on the list but as a floater? Lol I don't want to hold up other people I have alot of other stuff to do before I need it and I dont want to hold anyone else up.
