No. they will not work
stock springs are barely enough for a stock cam. I can take them and compress them a little bit by hand, that's how weak they are.
they'll PROBABLY accept the lift though, as they don't run into clearance issues until .500 lift, but again, you'll float the valves long before you hit 5,000 rpm.
I would consider running the Hughes 1110 springs or something similar. that's a good all-around spring that works for a lot of cams.

Patrick, where are you?
Comp 901s will work.

ask and ye shall receive.
comp 901's have a ~1.1" coil bind height. you'll get about 1.6-1.64" install height with the proper retainers, so if you want to leave .060 before coil bind, that'll leave you with .440-.480" max lift, depending on install height.
for this moderate lift, I'd use either the GM3100 springs and retainers, or for about the same price, hughes #1110 springs and either used 2.2L retainers or hughes retainers. that'll give you ~.040-.060" more lift capacity than the the GM3100 springs, for about the same price (if you're not junkyard scrounging)
