To me it sounds excessive but im not sure what "normal" would sound like. I have a intense stage 3 cam, 1.7 yella terra rockers, 7.4 pushrods, stage 4 intense heads, comp oer lifters. I took the valve covers off and spun the engine by hand and checked the pushrods and the torque on the rockers everything seemed ok. Here is a couple videos not sure how well you can hear it over the open exhaust. Im planning on checking oil pressure tomorrow just to be sure. Let me know what you think.
