What about the clutch driver and flywheel? Are the splines good on both? You mentioned new bearings, does that include main bearings also?

Machine shop fitted rist pins bored block. flywheel and clutch driver tight. Cam gear looks good but seems like coming from that area. Pulled clutch side off and checked cam bearing was good. checked other side was good. Plastic gauge rods were good. Just seems like in cam area. I reset valves a couple times. Thanks Doug
