Wouldn't the steep (relative) oem banshee piston dome have to be compensated for in the different roof angles between the main Trans and the secondaries
Where as a flatter pistons of aftermarket require different angles from from the roofs just because less hlll of a dome to get around
So many variables
I only reverse engineer buy a well ported jug look close compare it to other good running combinations practice on wrecked barrels and grind
Read and learn but deciphering who knows and who pretends that's an art
Some pretty compelling arguments but some are still only guessing but that's ok
