That Comp is the 248h at 192-200 duration.
I've not run that one yet but have a similar one (194-204) new in the box, bot it 4 same reason as you, near stock 250.
I'm pretty sure the 230/155HiPerf ran a similar cam (188-188 ie the 292 cam) from the factory in the 64 Chevelle so there is a hint.
The 350/300 Chev cam was near identical at 194-202, millions of them doing grocery store duty.
I do use this grind area (lo 190s, lo 200s) on every stock rebuild I do, just gives "a little more" but U cant even tell it's there at idle, just a tad more "hollow" sound out the exhaust. Good choice IMHO
