standard or HV oil pump?

The amount of road racing you will do will lead to all the other decisions. If you road race with any duration and frequency then you must have a thermostatically controlled oil cooler. This leads to a high volume pump which in fact does put more strain on the distributor gear. The distributor gear is driven by the camshaft gear which is considerably harder and notoriously sharp. The bad thing is that, in my case MSD, use cast gears as a standard. You must have a steel gear with most all aftermarket cams. I bought a ford racing steel gear and had a machine shop install it. Some things you can not do yourself without big $$ in machining tools. If you look at the link below I further helped the problem by providing more oil to the cam gear/dist gear contact. The picture is at about 40 psi which is all my drill motor would produce. By the way, my idle psi is about 35-40 and cruising is about 65-70 and cold is about 85. Simply drill a .040 hole in the right bank oil galley plug. I also recommend the oil pump in the second link along with a billet drive shaft. I have 4500 demanding miles on my engine without any problems at all.

There is nothing harder on an engine, car too for that matter, than road racing. Drag racing does not even come close. Almost all street and drag race driven cars do just fine on a standard oil pump.

I may not be an expert, but I did a ton of research before I bought the first part for my engine. It is still just my two cents.
