Tti headers

Hey guys I just got some tti headers because I got a new motor for my car. I figured the stock manifolds were killing a ton of power. Do you guys think I’ll feel a big difference or are headers a wasted? 360 10.1 compression edlebrock top and kit. What do you guys think? Also has anyone installed tti headers? Are they easy to install?

Dont know about the install. , but they will help a bunch , if ur tuned for them !
