The calve clearance adjustment was also neat - a tapered adjuster that you screwed in or out as necessary. As you say, I do know a reasonable amount about them and still rate them highly.

Very true - strangely enough i was thinking about the valve adjusters the other day and trying to remember if the grub screw with the "slope" machined on it was in the bucket tappet at an angle or perpendicular to the sides. Certainly a novel way of adjusting the clearances and did away with the need for shims and all that entails.
As you say, a very good engine!
