Opinions....best headers for '72 Duster
I learned a long time ago that it's better to spend a little more and get a better product than compromise because it will come back to haunt you.
Aside from the already mentioned benefits.....
* Don't need a 90* filter adapter.
* Fit Milodon deep sump oil pans.
* The 1 5/8"-1 3/4" step works good in a wide range of applications, from street to race. I've gone mid-11's with my 3,530+lb 360.
* Easier installation.
