Before Crane had all their financial troubles, my go to spring for this type of application was the 99893.
Ive used countless sets of those through the years.
You couldn’t get them for a while when Crane was in limbo.
The Howard’s spring I mentioned earlier is very similar.
I see you can again get the Crane 99893’s now, so those would be another option....... and they’ll also work well should the OP decide to step up to a solid lifter cam(well..... at least the old ones would. I haven’t had a set of the newer ones in my hand).
