I also removed as much casting flash material as possible to smooth out the internal surfaces of the valve covers. I also had to re-install the valve cover breather oil splash plates. They were somewhat secured with riv-nuts. I removed them and found suitable sheet metal screws and re-installed the plates.
Red circles indicate missing hardware. So I cut up 5 hex head bolts to fit in those locations. I will use JB Weld to keep them in place |
