Headers install, easy endevor or horrible

Well as it says I am debating throwing some headers on. I picked up some hooker comp headers for my 68 with a 273. They were a steal but looking at the install I am debating on just running true duals from the manifolds. What to you all think, worth the time and skinned knuckles? The motor is an older build stock setup, I did just do a ld4b manifold and 600 holley, so I want her to breath a little easier. Thanks all. :burnout:
