LT1 swap headers - out of production at Hedman

Common knowledge I guess, but I had to read a while to figure it out. The Hedman 48469 is the D port version of the 48460 (still made). Bummer is the 48469 is no longer made. For those of us swapping LT1 into third gen, it seems as though this was really one of THE better choices for LTs.

However Hedman makes the D port shorty headers 48479 so that means that still have the flanges avail for the D port. I contacted them about making another set. Maybe we should ask for a limited run of them?

I know there probably aren't a million people swapping LT1 into third gen though, so maybe that's why they quit offering. Everyone wants LS1 now of course.

Which makes it cheap for the LT1 stuff to some degree. Aftermarket is still about the same I guess.

I ran dyno don headers with lt1/lt4 gaskets on my fastburn heads.
