I had an awful thing happen while assembling the head, I managed to break one of the camshaft caps while tightening. I didn't notice one wasn't sitting totally flat, and it didn't take much for it to snap. Now I am seriously F'ed, I know these come as a set to the head. I think if I can find another one it will either be close or I can have it machined, definitely do not want to buy a whole new head. Have emails out to partsoque and amayama to see if they can sell me one separately. Otherwise, anyone else know where I can find a used one. It is the 2nd one from the front. if nothing else, let this be a lesson to all.
