this is for crazy68dart. eastwoods ceramic coating is good for 1,300 deg. i modified an old electric oven, made it 4'6" tall inside, just cut the top off the oven & used old sheet metal & wrapped with insulation. it's an easy job. it's not pretty lookin lol but it works. my old headers had jet-hot on them, they still rusted. had tti's, they rusted after 1 year, so i don't think any of them last. for 50 bucks u can do ur own. if they go south in a year or so, u can redo them. still cheaper than spending big bucks to recoat plus shipping. i sprayed mine, baked for 1 hr. they came out great. stay safe, seeya, Rick,
