Not sure what your local labor rates are, but I can at least give you some shop times.

The factory interval for valve adjustment is every 30k miles. Bulletproofing the VANOS (Beisan exhaust hub, solenoid pack, anti-rattle kit and timing chain guide) is a good thing to do “while you’re in there.” You would probably be looking at 6 hours of labor for that.

Rod bearings should be done by 100k or if the oil pan gasket leaks, whichever comes first. Your mileage will vary based on how the car is driven. Definitely let the engine fully warm up before giving it full gas or running to redline. You’re probably looking at around 8 hours of labor for that job. Other “while you’re in there” jobs would be motor and transmission mounts.
