What if it has been several weeks since the build, waiting on the final parts (intake and dual exhaust) to arrive? I assume some of the lube has probably come off everything. Pull the lifters and drop some extra lube down onto the cam? Or would priming the system before startup be enough? I've had the motor built 3-4 weeks sitting in the engine bay as I've been getting everything else put together. Still waiting on intake and exhaust (12bolt is out of stock on the dual exhaust for another couple weeks).
