Seeking Exhaust Advice

My question is, should I attempt to do it myself

I installed those Hookers into a 65 V100 wagon..... in the mid 70s. I was born in 53. I borrowed my Dad's tools, and had at it, no templates, just trial and error. It turned out beautiful.
The short-block was a 340. The cam was a factory 318, as was everything from the decks up, including the 2bbl. That is my all-time favorite combo. The A904 died first. I then gave the car to my lil brother,10 years my junior, along with a good slanty, and he put it back to stock. She drove for several years after that.
I do not recall what ever happened to those headers.
If a mid 20syear-old, hi-school drop-out, like me can do it, with borrowed tools..... I suspect anyone could; HAVE AT IT!
