[Rich-L79]

Bone stock L79 in a '65 Chevelle, 3.31 gears: 14.93 @ 91mph.

I noticed no difference with or without the check ball, Holley very much strongly suggests NOT removing the check ball. I was running the stock spring when I logged the time slip noted above, I've since switched to the yellow spring. I don't know if that would net any better ET, but it feels smoother on the street.
