That 924 is a very common flat tappet street build spring, not enough for heavy hyd roller stuff
If it were mine, I wouldn't spend a penny until I saw what my actual installed height and spring pressures were, you are likely to be even lower than what the paperwork says
Then I would go with something like Barry said, or if the budget is less forgiving, a high quality standard spring with damper that that matches your installed height and lift.
The factory Edelbrocks may be good for this application too, but you have to measure installed height, calculated or measured lift, and the resulting pressures.
Sounds like a lot of work, but less than an hour of work for the machine shop if you showed up on his door with one head. Even less time if you measured installed height on the car and calculated the rest, then he just measured spring pressures for you
