Default Newly Minted 257/WRX hybrid -- rod knock or noisy valvetrain?

Hey guys,
just wanted to thank all the guy on here, especially DrinkAV8 and everyone else who has posted up their hybrid build stories -- I'll shortly be doing the same as soon as I can get the kinks worked out. Those include:

1) chattery/shuddery clutch (ugh)
2) strange knock/tick from the driver's side

EJ257 shortblock (new)
cleaned/decked WRX heads
STi head gasket
stock turbo/accesories
downpipe, prodrive axle back

I noticed this knock/tick shortly after starting up the engine...though I'm not exactly sure it was present during the first time that I started my new hybrid up. The noise is RPM dependent, and at idle I estimate about 350-400bpm at my 750-800rpm idle (worrying).

video of my problem:

haven't taken a look at the oil yet, but thought I'd get some opinions here first. THanks much.
