I used the copper gaskets and the Stage8 bolts . As I remember (A) to the original part number made the bolts a
1/4" longer to take advantage more of the threads available in the alluminum heads and I have the CobraJet heads which have both bolt patterns full sized car and truck (over and under) and Mustang -Fairlaine (in front and back) of each port. With the ends of the header flanges bobed I have 14 bolts per side all tightened and locked. The center two bolts on each side had to be wired because the locks wouldn't fit against the header tubing.
