For a Pontiac application the Comp Magnum hydraulic flat tappet 292 H would be somewhat similar, but probably less seat duration. I don't know at what tappet lift Olds factory cams were rated at, the Comp is at .006".
The Comp lobe has a bit more lobe lift.
Same .050" duration.
292/292
244/244
.3340" / .3340"
.501" / .501"
110 LSA
( Comp lobe 5209 )
Or lobe 5204 listed on page 11 here:

Same 292 & 244 specs but lower valve lift like the W-30 cam
