dart headers
25 years ago when I put the cheap headers on they never fit. I dented them all up, bent the tubes etc. Now here we are all these years later and I find out my engine just does not sit in the car correctly.
Even if you don't run TTIs go to their site and down load their Installation Instructions which have specs on where the engine is supposed to be located. Getting it in the right location will help those other brand headers fit as well.
