I would appreciate your thoughts – I am rebuilding the cylinder heads on a 3.5 v8, carb version, from a Discovery 1 which has 75,000 miles on the clock which I believe to be genuine. I am going to re-grind the valves which all look good and no play in the valve guides. Question - is it necessary to replace the valve springs? Springs themselves look fine and tappets are good with minimal wear, very minor rub marks where they have sat on the cams.

Whilst asking, the official Land Rover workshop manual says nothing about replacing the head bolts so I assume they are ok to reuse?

All comments are much appreciated!
 
Sure the springs can be measured, specs in the manual?
But at that mileage I wouldn’t expect them to be an issue.
