Hey all, I am rebuilding a cylinder head in XJ600/ FJ600 and I just measured valve springs free height. To my surprise in case of all outer springs it was 3-4 mm over the specified height and for the inner ones it was 3-4 mm below the specified height. The manual doesn't say what is min - max height allowed so I assume the are worn and to be replaced. Is this normal sign that valve springs are worn?
