Been there, done that.
I tried to mount the Mr Gasket starter shield that I used to have on the BBC in my '67 K/10 Sub -- it wouldn't fit the 350 with the headers in place. Not enough room. So I tried the soft aluminum/ insulated wrap-around heat shield. It fit, but possibly held the heat in.

Anyway I pulled the headers out of the oven a day after baking them. There was some ugly bubbling that ran off and gathered on the under side. Unsure what it was. Now we know why Jet Hot charges so much. They can afford to re-sandblast, re-paint and re-bake to turn out a professional looking product. I decided that if the Pharoah had leprosy, wrapping him up like a mummy would hide it for 3000 years. No one will ever know.
So I wrapped the headers in 2" tape. Jeez, what itchy stuff!
But they look good.
