The springs in the kit are 1.32" diameter, while the 987's are 1.43" diameter. I couldn't find any specs on the LT4 Hot Cam Kit retainers.
Otherwise, the 987's should be fine.

Those will work but you need the matching retainers.

Replace the retainers, the hotcam retainers are junk. I had one fail and that was was with plenty of bind clearance.. these things suck. They are paper thin right on the chamfered edge where the spring sits. A wider spring will even make it worse
