T`was not until I was involved with Lotus/Jaguar that I discovered that lovely quiet valve clearances were indeed a sign of danger ahead and the possibilities of burned valves and seats, for it seems for whatever reason Jags valve clearances may be prone to closing... Don`t ask me how that might come to pass, I just remember finding tight clearances were the cause of a hard to start Jag I once owned and also tight clearances on an Elan.. Go figure..?
Where is Spanner Juggler AKA Colin when you need him, Colin was ever the one who kept us informed as to the shortcuts and tricks of the garage trade...
