Naw.. mark the pushrods and watch them like this in the video.. if they are all moving you are fine, if not.. find the issue quicker than later and worst case would be pulling it apart to clean any metal out and put back together... new cam and gasket kit..
THat was a good video. Err on the side of caution now days with cam installations. I wonder how many have problems if they assemble an engine and don't start it for 6 months?
