This right here illustrates the problem of trying to build a motor based on bits and snippets of information picked up, sorta, from posts made by people who almost think they kinda remember hearing somebody say something about having read a thing in a book back around 1975 or so.
The rods go the right way round in the engine. If not, you create oiling problems for yourself.
The pistons go the right way round on the rods if you want the engine quiet. If you want to fractionally reduce friction, you can turn the pistons 180°, but then prepare for the engine to sound like it's going to think about chucking a rod until it warms up…every time.
Wrong tool for the job.
…is money you're going to spend anyhow, long rods or no long rods, to get the surfaces flat and the combustion chamber volume where you want it.
Spend wisely and that's doable.
