There are two ways of doing it:
1) Cheaper way - use the FMS kit you mentioned, which will require you drill & tap holes for the spider bolts, and use a small base circle cam. The small base circle cam is required because the lifter bosses in your block are too short to hold the roller lifters if you use a regular base circle cam.
2) Use lock bar lifters like the ones from Crane:
Crane Lock Bar Lifters , and a regular base circle cam.
