i got rid of my headers it wasn't worth it for me . for one had to pull passenger side header to replace starter plus the constance leaks plus on my f-250 4x4 highboy i didn't notice a difference so i converted back to stock manifolds now nice an quiet an i still have gobbs an gobbs of power . well thats my 2 cents

Yup, those are the right ones. I've had the same ones on my '75 for 13 years with no problems. In fact I run nothing but headers on my vehicles since my engines would probably choke and die with stock manifolds. It's true that you have to pull the right one to remove the starter but how often does that happen? The key to preventing leaks using good gaskets and keeping the bolts tight. Throw away the gaskets that come with the headers and get a pair of these fel-pro's.

Stage 8 locking fasteners are a good idea too.
