Hi again timing chest cover is now off the Cams of my 1954 Comet are MK1 the followers are worn as is the cam profile, I need to have both stellite coated any ideas how long this will take and where best to go for the work to be done please. My Comet also has aluminium large and small idler, and a fibre ADT wheel would also like to replace these. The project moves on slowly.
