5.7 Hemi dealer says needs cam and rockers on driver

I looked at his info on his truck
Idle Hours-1360
Drive Hours 4300
total miles 123,000
This kid sat parked in his truck for 2 months straight
No it’s not a diesel.
Idle time and lack of regular maintenance are the key factors related to this type of failure. Chrysler first became aware of it when police fleet hemi chargers started to fail.(cars would sit and idle all day)They released a tsb or starcase about this to dealers about 10 years ago
