Re: shovel rockerboxs differance

From your description I believe you are talking about the air cleaner support bracket mounting holes; probably not an issue unless you are using a stock air cleaner. The large boss was used on late heads. Another difference is that later boxes employ two short studs rather than just one as the earlier heads did. Most repop rocker boxes are set up for the second short stud and come with a spacer so you don't have to change from the long stud on early heads.
