Default New built motor oil leaking from tgv gasket area

I have a 04 Sti with iag stage 2 block
I started getting a leak of oil between the head and the tgv. The gasket has oil on it and it’s pooling right in front of the tgv on to the top of the head. Currently in break in period so a lot of vacuum deceleration. I do have a iag competition AOS. Currently 200 miles on everything new. Not much of any smoke from exhaust either

I have no idea why it could be leaking oil from the intake manifold “only on driver side”... unless extreme blowby or the AOS is not correctly working could AOS be clogged or the drain line be pinched?

Any advice would help

I would look at the small oil plug for the head on the flange where the TGV bolts up. If it's not tight you'll get a leak similar to what you're talking about.
