Thanks Peter, I appreciate the info. I think I know which way I'm going with regards to "air out".

Since the heads are at the machine shop I wanted to do some reading up on what happens and what they do, just get some basic general information. So I pull open Wayne's rebuild book. I was reading camshafts and since my 964 cams had just come back from Elgin cams my interest was fairly peaked. Then the book started talking about the rockers and they should always be hardened and polished during a rebuild. I didn't think they needed to be redone as well especially sice when I took them out they were in next to perfect condition. How important is it to have them done? During the disassembly both the Bentley manual and Wayne's rebuild discuss the importance of marking the location as to which the rockers were removed from and reinstalling in the same location. If I sent them off to a machinist, how do I make sure they get put back in the same place so they are installed in the same location? If I installed them the way they are without any machining, what do I risk?
