| HV pumps require a HV pan. |

You can try installing a HV pump with a stock pan, but if your car runs like a stock CJ, you'll likely hear lifters on hard corners and your oil light may flicker on when going through the traps.
The #1 oiling mod for any fast FE is a new pan. Adding a performance pump (HV or HP or HVHP) requires numerous mods, the least important of which are drilling out oil passages, the most important are proper restriction of oil to the heads and assisting rapid oil drainback from the heads by using such items as 1958-66 style pedestal drip trays which have the three drainback fingers in them.
Also, replacing rod bearings with the non-squirting type of bearing shell (squirt hole not present) will also keep pressure in the crank while the extra pressure/flow allows plenty of cranksplash for the cylinder walls. Note that rod bearings can only be replaced if your rod passes roundness spec or is resized to a perfectly round shape.
A performance pump has caused the death of many stock-panned FEs. Run a stock pump and an extra quart of oil (as all 428CJ dipsticks since early 1969 were calibrated to do) if you don't wanna drop the bucks on a performance pan. Stock pumps work great.
