Stock 360 Upgrades for Crusher Cuda?

I really like the TTI headers, but a lot of people have commented on other posts about how bad they fit. These are in my price range uncoated, and I believe would flow better than the "Spitfires". I'm not an expert. Just my observation. I hate to spend $720+ and have to beat them and heat them.

I haven't heard much about installing these TTI headers being difficult although I am very interested to hear any comments on here about them. I'm planning an early A Body build and this stuff would be good to know when planning powertrain. I'm using TTI in my present car and the install was a breeze!
