[86.5 7MGE]

For the tensioner you have to buy it seperate. I have heard of people replacing them but not too often. Also, as far as the HG lot of them with that has high miles on it won't show many signs of a BHG even though it does have one. The factory HG is good but if your want to have a better HG seal a Metal HG with ARP Studs or Bolts will do the trick. But wait to order the MHG because you don't know how much the machine shop will take off your head and it comes in different thicknesses.
