Ok, So I need to replace both head gaskets. how long will that most likly take on a 2002 dodge durango SLT 4.7L

 

a 'B' level tech should be able to do it in about 10.2 hours (standard flatrate time)

a garage mechanic (entry level, 'C' level tech) (i'm assuming you are one, no offense) should take flatrate x 1.5, so 15 to 16 hours
