header wrap? pro's / con's

I run uncoated TTIs and aluminum heads. Plus A minimum water temp of 205. It is hot as Hades under that bonnet . Before I put the carpet in, I put some insulation down, not dynamat. I haven't noticed the cab particularly warm.
I ventilated my hood.
I don't recall anyone in hi-school running header-wrap; I was 18 going on 19 in 72. Shoot most of us never heard of header-wrap,lol.
