blykins speaks the truth. The FE's are a little antiquated in that they utilize a long Rocker Shaft to support all the rockers. When I think of Rocker Shafts it takes me back to the days of racing 4 cylinder 1275 CC Minis and spinning them to 8500 RPM. The Rocker shafts inevitably wear when spring pressures were increased. I think the same hold true for FE's. If the shaft becomes worn, the bushings in the rockers wear then you're chasing your tail.
But the tapping could be one of many things. Look for witness marks on various components.
