We build a lot of circle track engines for the last 35 years or so and we use a lot of 10552 and 10553 pumps, Plus we building alot of engines with .903 lifter bores which will bleed off a little more oil. But the 10% more volume pumps seem to work very well.

On our Honda rod and 283 main engines we use the standard volume pump and still have to drill another bypass hole to keep the oil pressure under control.

I also use the drve pump which is a low volume drag race pump onn some of my build with zero problems.
