Found a source for the special valve adjust tool for $300. I never let anyone else work on my cars, so special tools are part of the price of entry. But I have no experience with this engine. Do the valves drift much or is this a once in a blue moon adjustment?

I found the following in a section of the service notes:

2. Valve Clearances
a) It is unlikely that valve clearances will require adjustment unless components are replaced. A single forked rocker arm is used to operate a pair of valves, which are shimmed during manufacture for equal clearance. Routine service clearance checks should be made between the cam and roller follower. Only if a valve or rocker arm is replaced need the clearance between individual valves and the rocker arm be measured. Adjustment procedure is detailed in the text.

So it doesn't look like anyone expects to really have to reshim the valves unless there is significant disassembly. I will hold off on buying the tool
