Thanks, Bill
Glad you find the mods interesting Actually, there wasn't enough room to lay it all down...
As to your q's: 1) No, no performance issues, they may just leak a bit over the slip joints if you won't clamp them. Actually they shouls be welded, but I wanted the option to use this header on another engine in the future, so I clamped them.
2) I never had a need to route the breather box to the intake. Some say the oily fumes make your octane rating go down and with 10,8 Compression ratio on pump gas, I didn't want to take chances for now.

'75 Super.
