E-street vs Promaxx vs 440 Source
In the pic of the valve tips you can see the distance from the top of the lock to the top of the valve is longer on one valve(exhaust).
The “big” spring was the oddball one, and it was installed on the exhaust(the shorter installed height position).
It was installed short enough that it was at about 200lbs on the seat, and in coil bind at barely over .500” lift.
How can you miss that?
I saw it as soon as I put the head on my bench.
You can also see the difference in the height of the retainers is quite a bit more different than the height of the valve tips.
