Yep, they're really stainless. I questioned it myself at first. The come with port gaskets, but no collectors or collecter gaskets. I just bought some collectors and the aluminum gaskets from a local hot rod shop.

Did you have any fitment issues with these headers?

68Stepbed · 12-17-2012, 04:45 PM

I had to grind a small section of the engine block where there is a big squared off block that sticks out. It's my understanding that the iron blocks don't have this issue. Also, where I'm running a 700R4, the inspection cover mounting "ears" interfered with the collectors. If you're using a 4L60E, this isn't an issue at all.

Also, there's no O2 bung in these, so an exhaust shop will have to weld one in the pipes.
