    You can't tighten down the cam caps too much. Well unless you strip them out. Sorry to say you will have to get the right cams or have your head and cam caps machined.

      +1 chef. And If you could tighten them up that much the bolts would break or strip the head

      Helps to have a defective torque wrench too Been there


      If you use that cap your going to have to machine the cam or the head and cap.

      However, with mine it was just the cap that was tight.



      I took one off the old head, (A,B,C,D) Mine was cap B.

      It seemed to rotate just fine without any play so I checked with plastigage in a few spots and it was within spec.


      hope this helps.
