Over $6000 to install TTI headers on 66 Barracuda

wow, I have been blasted on this thread. Some of it is deserved so I am not offended.

The two main reasons I take the car in to have it worked on; I really do not have experience working on cars. I have been collecting tools and creating a space to do more work in my garage
Time - my job consumes a lot of hours, coaching my kids teams or being involved in their school/sports, family and other commitments. So it comes down to priorities, mine is with my family.

With all that, moving forward I will be doing as much work on the car as possible.

And thank you to several people who have been helpful - with guidance and advice.
