I suspect someone in the past used the brass spacers to fill the space, not realizing that brass is a pretty good conductor of heat versus phenolic and why the phenolic was used. I know the first time I worked on my 40 120, I didn't know why that funny stuff was in there, and why the bolts that didn't fill the holes were used. My 51 200 had the phenolic ones.

I would suggest that you get some of the phenolic tubing mentioned earlier in this string and replace them. But if you aren't having any vapor lock problems, then why bother.
