904 transmission shifting adjustments

The rocker shafts have a specific orientation. look on the ends. there is a little notch there. The notch always goes to the left and down. On the passenger side left is up by the firewall. On the drivers side, left is up by the rad.
This is done this way to align the oil supply from the rocker pedestals with the oil access holes in the rockershafts.
For street use I leave some accumulator spring in there.Is this car gonna spend time on the street? It's a personal thing. Without any spring in there at all, I find the 1-2 shift rather violent. Especially with the KD tied back like that. BTW, that lever should be tied to the tranny itself and not to the chassis.

3" pipes are loud, no matter what. I am very happy with my Dynomax 3pass mufflers.
What brand of headers are those?
What are the cam specs? I googled and came up with nothing
8.85 compression ratio? Is that thing set up for supercharging? As far as 340s go, that's pretty low.
What stall speed and rear gears are you running
