It may not have been such a great deal at $80. I broke it down today and the main cam journal is badly scored. I know the cam just rides on the head and rocker pedestals without any bearings, but I see cam bearings listed at parts stores. Do you just and overbore the cam journals and caps and install bearings? There's a guy in town who does good work pretty cheap, but I'm probably looking at another $150. This is getting to be worse than my Jeep was.
