Harland Sharp roller rockers...worth it?

Intended cam specs should be as follows (or as close to it as I can come)
Hydraulic tappets
Lift: .450/.475
Duration: 298/308
compression between 10.5-11:1
1.88/1.60 "J" heads
Eddy Torker w/Holley 650DP (to start with, this combo may change)

Not a high lift cam by any stretch of the imagination.

With that small cam no need for roller rockers..i'd dump the 1.88's too....
