Does anyone know anything about HD Factory performance heads, have an 88 FXSTS with a sticker on the frame stating that the bike is fitted with 'Factory Performance Heads' but I can't find any information on the heads? Can anyone help?

nothing like a good head job 

 

Yep...I got that book and it's friggin good!

Hey Dave are you aware if Donny Peterson has written or released any more of his informative volumes of work ... I have the first 3 but would love to have a read of a couple of his other ones he had in the pipeline .

Cool , Thanks .

Thanks Dave, first Harley I've owned so the info is much appreciated, I'll buy the book you suggested it looks like its got some great stuff in it.

we need a STICKY of 'good reads'
