Bring a cordless drill and a primer, and a oil pressure test kit. All cheap, easy, fast, and allow you to check the oil pressure (you'll need a couple quarts of oil and a filter, they should have that). Also, remove both valve covers and inspect what you see, also rotate engine while priming to verify the oil comes to the rocker assemblies. Bore-a-scope would be handy too
