Other than a feeler gauge etc, what's the clearance specs, and is there anything else I should know?

Perform a leak-down test to make sure the valves are sealing. You might have to de-carbonize first.

The valve clearance is 0.10 mm. It does require a special feeler gauge to adjust. You can order part number 4180 007 1005. This is a kit that will include the feeler gauge, valve cover gasket, and copper sealing washer for the valve cover bolt.
