Re: headers, 1970 c10 5.3
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.
