stock springs might coil bind with the .474 lift alone....
I'd use comp #901's with stock retainers and locks.
the #901's will be borderline with 1.6 rockers (makes your .474" lift cam .506").
could also look at hughes #1110 springs. should work with stock retainers, and they have enough lift capacity to handle 1.6 rockers.

borrow/rent a valve spring compressor (looks like a giant C clamp) or if the heads are already on then use an on eng valve spring compressor (it has a shaft that replaces a rocker shaft then a lever that slides on it & you pull it toward you to compress each retainer/spring) and use shop air w your compression tester hose or 2-3 feet of 1/4" nylon white rope fed into the cyl to keep the valve from dropping as you R&R each spring/retainer.

I'm assuming comp 901's are a single w maybe the dampener strip inside (which (a single) eliminates any step issues on the head surface and on the underside of the retainer). If the OD is correct and there is no coil bind issues then yes just R&R

both springs I mentioned are single w/damper and ~1.45" OD, which should drop on. the comps are ~90lbs seat pressure at a ~1.66 IH and like a 1.12" coil bind height with a rate in the 350 lb/in, the hughes are ~135lb seat pressure at a 1.66" IH with a 1.04" coil bind height, and a 345lb/in rate
the comps are $65-70 thru summit, the hughes ones are $90-95 from their website.

yes, I used the 901's on a 360 and a comp XE262. drop on and go. while you're at it, I'd replace the valve seals....

not worth the performance increase over stock. 318 closed chambered heads, I presume they're 302 heads? they peak flow ~.450" lift, you wouldn't gain anything by opening the valve more than you are now with that cam.
