I just picked up a set from the neighbor for $100. Just wondering what I can expect to pick up in hp and on the track. .2 hopefully? Also what is the best way to go about putting these bad boys in? I hear its a royal pain in the @ss. Just need a few answers.

First off, who is the maker of these headers? There are a lot of brands out there and some ARE better than others.

Since you have an LT1, they will be a pain but it is doable. I would offer to help if you would like me to. I installed a set on my car and, well... at least I have experience doing it.

Normally you gain a few tenths. And perhaps a mph or 2.
