well, given how much you have going on in there, it could really be as simple as a tolerance thing, and the thicker oil takes up a gap enough to quiet it down.
you're not going to hurt anything by running 20/50 (except maybe on a really cold morning at startup). it's just not going to give you any benefits on a street car. but with the stuff you have there, i tend to suspect that it's not really a street car (defined as 100% daily driver grocery getter reliable with no issues. not defined as "i drive it on the street").
