As a general rule any engine that runs less than 7,000 RPMs does not need either a deep sump pan or a HV oil pump.
Having said that if you already have the canton pan you will benefit from the HV pump - the reason you should stay with a stock style pump on a normal oil pan, is that during high RPM launches and power shifts you can actually suck the pan dry - not the case on the 7 qt pans.
