i was wondering what was needed in order to properly install a header wrap? ( besides the wrapping itself )

 

A clean header. You will probably need to take the header off the car.

 

but is there a special way to do it ?

 

A clean header helpful.

Soak wrap in water, wrap around tubes, overlap at the start to prevent unwrapping, clamp loose end. Allow to dry some, drive car, exhaust heat will finish drying and the wrap will shrink slightly, keeping it in place.

 

better than header wrap buy the one that just has little clip ons.
but if you decide the header wrap way.

have the header off the car best way.
wet wrap
wrap around header "stay away from welds"
let it dry
then spray with high temp header spray
let it dry then install.
