Does the R# cast in the cam relate to the year or is it just a casting code of some sort
I have cams with numbers ranging from R0 to R14 I even think the yoshi cam I have has an R# on it as well. At the risk of being told just use the yoshi which cam should my 69, 70 and 78f2 have. Will I have to measure them? If that is the case how is this done.
Thanks in advance
Steve
