On a Ford with a high volume pump I would insist on an upgraded oil pump drive shaft. They will also put more load on the distributor and drive gear and can contribute to spark scatter. Top speed racers tend to use standard volume pumps because a high volume can suck the pan dry over the course of the run.
Would I worry about it? No. Do I use them? No.
Engine machinist and builder here. Stone hones work just fine for high performance. You just use different stones for racing or high performance applications. You probably used something close to a 318 or so, but you could use a 625 or even up to a 818 if you wanted a race cylinder.(I may be slightly off on those stone numbers but I'm very close. They vary.)
Painting the lifter valley is very unneccesary and can only lead to trouble if it starts to flake.
These engines don't have drainback issues to begin with. Deburring and radiusing exsisting drains are good practices when building an engine.
If you change the oil regularly and run the engine nice and warm, that engine will stay clean for a long time. I'm sure you knew that though, you don't sound like an idiot!![]()

Next ive applied several coats of high heat clear to the distributors casting above the block surface..Im hoping this will resolve pitting of the repolished casting..for this truck does sit under a car port exposed to climate conditons...something i hadnt thought of in my initial installation...Sorry Austin!
