1970 Chevelle SS 454 LS6 Rebuild + Details

[XXXGoldL34M20]

Here is the LS6 Smog with Exhaust manifolds Restored and ready to go.
Some numbers i can't figure out?
Also let me know if these are all correct smog parts for the LS6 (Pretty sure they are but i just want to confirm).
All the smog hoses and clamps are the originals.
The picture of the Exhauast shows i grinded off the flap, Drilled a small hole and added a cotter pin to keep the side of the bar from sliding, I figured why bother having the heat riser with the flap if the car never gets used on cold days!
The Exhaust heat riser will still operate but with no Flap in the damn way (free flow all the time).
