On the front right side of my head it says PCB HF-1 you may have to take off the heat shield to find it.

would the manual f20b head have a different casting number than the auto version. Because the manual has a stiffer valve train and type s cams right?

[Jarrett]

It's the same casting number.

any thought on why the F20B would come with a Red cover and not blue? and is there any easy way to tell if you have the sir or sir-t with out taking things apart. like would there be a stamp on the end of the cam shaft? like can i pull the dizzy off and look at?

i just wanna more in more detail what ive got, also ive seen ok wiki rev limit is 7800, however ive read around on other forms that pl have taken it up to like 8500.

basicly i don't trust wiki on this info.
