Timing chain replacement
And don't reuse the dampner/pulley bolt..get a new one. & while your at it put a Melling hi Vol pump on it.....I would expect (w/good syn oil & reg maint) that you will not need to touch it for another 100K miles & if you don't have open hoses hanging down to the ground for breathers. These motors are unreal! Seeing them go 200-300k miles & still be pretty good runners.
