OBX Headers a heat concern?

Swain Coatings in New York does a great job.

Mine were done by Cerakote At Northeast Coatings. They are right down the street from me. Cerkote has regional certified application specialist. They worked out very well for me.

I bought the Maximizer sandblasted headers on sale. The sandblasted finish worked well for coating them.

Here is everything you will need to install headers on a 1990 ZR1. I hope this helps someone save lots of research time.
(1) O2 sensor extension
(16) header bolts
75' of 2" header wrap
High temp silicone spray
Paul Workman's dipstick bracket
Dipstick seal from Jerry's Gaskets
Stainless zip ties
Jerry's Gaskets header gaskets (do not use gaskets supplied with headers)
Headers!

Old thread I know, but I just got my new headers (OBX) back from the coaters,( I used local guys that have been doing powder coat of all of my parts including the top end of the engine), it is a very high temperature coating but it is not as good as Jet Coat or Swain, so I am also going to wrap them in DEI Titanium wrap. I would like to see pictures of wrapped headers as I am not sure the way I am going to wrap the runners that are too close together to wrap individually . I was also concerned with heat to the (new) clutch lines and electrical connectors. I currently plan to wrap the headers to the end of the faux resonators only. Any thoughts of additional heat shielding on the tunnel or anywhere else? I did heat insulate the drivers side interior cabin with adhesive heat barrier mats.

Might want to do some research before wrapping those.

There seems to be a concern over issues with moisture being trapped under the wrap which causes corrosion and rust.

OBX headers are stainless so it might be OK, but definitely an issue with steel exhaust pipes.

On my '66, I used insulating blankets on the exhaust pipes. They are open on the bottom but provide a heat barrier between the pipes and anything to the sides or above.

Here is a good place to start and someone to ask about wrapping headers.
