In order to remove the old studs I coated them with PB Blaster and waited. I then double-nutted them and they came out quite easily. If they give you fits with double nutting place a flat washer between the two nuts before you back-tighten them onto each other.


TIP: Double-nuts is a good trick for removing studs. Spin one nut onto the stud and then another. Now tighten them hard against each other, not to the stud. You may now use the inner nut to beck the stud out. If you have room, placing a flat washer between the two nuts minimizes any slipping....


Once all the studs are removed you will then need to remove the old manifold gaskets and clean the three exhaust port flanges. I used some acetone and a 3M Roloc disc by hand, not a drill. Alternatively some burgundy Stotch-Brite will work too. These gaskets come off pretty clean..
