Is there any reasons why a high volume pump shouldn't be used on a relatively stock 440
Drag, windage, sucking the pan dry.
You can always put a different spring or put the adjustable setup on a stock pump and have more than enough oiling for a mild 440. Heck, even the bone stock setup ain't bad!

If you are running tight bearing clearances, all a HV pump does is pump more oil through the pump relief valve. That additional oil flow has to go somewhere.

Hello Over 26 years of engine building I have aways put HV pumps on all engine ! not any trouble with any of them! On the street or on the track.I have them on my Hemi and our SixPack and they get run hard all of the time .Thanks
Really? You've used them with stock pans and never had any oil pressure issues under acceleration? Maybe with the 5 quart Hemi pan it isn't an issue

in your case none. Take it apart & clean it & check its' clearances & run it. eats a slight bit of HP/slightly stressed the hex but that's a non issue. If you had EXTENSIVE oiling mods starting with 1/8" under the pickup to all the way thru the system/loose clearances/high rpm then you'd wanna purchase a hi vol/hi psi or add a high psi spring or shim the regular spring in a hi vol pump & if not a regular sealed power pump is cheap/adwquate but you have the hi vol in hand so I'd say go ahead & finish & get the pan buttoned up & you'll be ready to move on to the next issue. EDIT I feel that a pan cannot get sucked dry and reports of that (low psi/fried journals} are due to especially inadequate pickup/pan clearance/lack of oiling passage mods/inadequate journal clearances

I have always run an HV pump on everything, SB and BB, all with stock pans. Even ran one on a 360 that turned 7500rpm with a stock pan, and ran 10.60s. Never a problem with sucking the pan dry

I guess if you're using stock heads the oil would drain back easier with the huge openings in the heads. The aftermarket Stealth and Edelbrock heads don't have that, so it's easy to suck the pan dry when running it hard with an HV oil pump.
Once you are at the pressure of the relief spring, the high volume pump does not put any more oil to the motor. It just recirculates more oil from the pump relief valve back to the pan.
