GM #89017825 is the superior kit
Felpro MS98014T is the next best thing to GM, but does include some unnecessary parts
Dorman 615-717 is all plastic, JUNK
Use the Dorman 47065HP metal elbows, but replace the junk Dorman o-rings with GM

thanks for the replies...next question is about install.... I need the installation order especially when the serpentine belt goes on for the following items: New Dorman upper intake with metal stove pipe, lower intake (NOS GM), complete belt tensioner with metal coolant tubes, power steering pump, alternator..etc. I am most concerned with when the install the new belt. should be done. I remember it being behind the tensioner but it's been a while due to working on this after work since January. I also am installing new pass side motor mount. I would appreciate guidance on this. I bought a FSM but it doesn't help with all these items being pulled off. I would appreciate any pictures as well of a stock 3.8 engine as I am also replacing all the emissions vacuum lines, cruise cable etc. I will also take advice of there all should I put the "right stuff" black RTV. I plan on installing the LIM gaskets dry with RTV in corners. Should I RTV more or anywhere else? (this is a first gen car with the smaller side gaskets. no alignment dowel LIM). Thanks in advance.
