As I continue my search i noticed that on the cover of the jake manual for -71/-92 series engine they mention it will work on4 or  2 valve engines.  This was news to me as I had previously been informed that you need something special (or very old) to get jakes to work on a 2 valve -71).  If this is not the case it is going to be much easier to find jakes for my 6-71. I have searched the jake site for this info but it doesn't go back that far, maybe there is a jakes forum somewhere (I'll have to look into that)   Thanks as always, Patrick.

They can be installed on a 2 value head. It takes a  cap on one exhaust value instead of the bridge over two exhaust values on the 4 value. I have some of the caps, instruction and parts break down.
