My heads!

[stlmikie]

How does a guy tell whick heads are on his bike? I have the 03 Mastiff with the 107".

heads or rocker boxes? should be S&S heads - its stamped on them

the TP rocker boxes have four bolts on each and the S&S have 6

The reason I asked is Mr. Woods wanted to know so as that he could tell me give me some options for the cam and springs that I may be getting. Any idea about the stock compression on this beast either?

should be able to call BDM with the build # and they can give you all kinds of info about your bike.

Truth. Just did this last week.
Can also go to their website under customer service and submit an email. They got back to me within a day.

Is there that much of a difference between the cast and billet rocker boxes?
