To my knowledge the 603 engine does not have adjustable valves, they are hydraulic. If there is a problem with tight valves then you may need to perform a valve job but that is another story............ Start with the GP's as suggested.
If you need to look further than the GP's there are other items which contribute to cold start problems. You may be required to do some inspecting and adjusting...............no biggie!
