It's one of those things, you may have a mechanical problem with the valve train (lifters, valves, rockers, etc) or you may want to try some type of oil treatment. Oil returns to the pan when the engine hasn't run in a while, oil treatment may keep the heads lubricated better for that first start until the oil pump can build up pressure. A good degunking may help too. There are plenty of products to add to oil to degunk an engine. Hopefully in your case that is all you need.
