Source for NOS oil pressure control springs and pistons?

[mclumber1]

I'm trying to nail down my low oil pressure at idle when my engine is warmed up. My temps are fine, my oil pump is good, I'm running a full flow setup with a K&N filter, pressure switch is good, and right now it's got 30w rotella.

Last year I replaced my old springs and pistons with the pressure booster kit, and I think it was cheap empi crap. So now I'm searching for NOS springs and pistons but I'm not having much luck. My engine is a dual relief AK engine code 1776 with a doghouse shroud and all coolin tin. SVDA dist. and dual Weber ICTs.

You know, after reading Jim Gilmartin's thread ...

... I would be inclined to find a way to test any springs to see if they are in-spec in terms of strength.
