you will need to order:
1 - Exhaust Manifold Gasket $ 18.80
9 - Self-Locking Manifold Bolts $ 2.66 (each)
Both can be ordered from
http://www.hondaautomotiveparts.com The helms recommends changing both the gasket and the bolts whenever the manifold is removed. You need to torque bolts to spec, let the engine warm up (take her for a drive) and then once she cools back down, re-torque everything to spec. All other gaskets/hardware come with the header.
