Also heard that many Alfa racers simply remove the cam locking "key" and rely on the morse taper at the end of each camshaft being robust enough when the retaining bolt is tightened up to work perfectly well and be infinitely adjustable. As the factory morse taper plus key is a "belt and braces" option I'll probably stick with it and file the holes if I need fine adjustment.
All credit given where due to those who made and posted the photo's of the tools. I'm only posting this to make is easier to find for anyone in future - especially me !
