Black top S13 SR20det stock internals and Metal headgasket

It lets out a little white/grey smoke out of the exhaust during idle not a ton but a little and puffs out more when starting the car up on a cold start. The car then doesnt smoke as much when driving at warmer temps. It then will only start smoking again when pushing the car hard and blows out smoke again only during shifts or releasing gas after boosting.

First we thought it was the turbo, and because I had a brand new tomei turbo sitting in box, we swapped it out for it along with new tomei exhaust mani, tomei turbo elbow, New testpipe, new downpipe, and tanabe exhaust. Car was still smoking..

I had my head done (Tomei cams, retainers, valve springs.. etc..) new valve stems and valve cover gasket.

Car was tuned each time we changed something out with Power FC djetro. Car runs strong. Did a leakdown test, and compression test and the numbers were solid across the board and even. So we assume it cant be the rings.

At this point the smoking has improved to not as much as before, but still smokes. Can anyone with experience point me in the right direction of what might be the issue? or is this normal?

The tune is solid, A/F is solid 12 across the power band, smooth and strong pull when turbo is at full boost and i have had no issues with the car since purchasing it from previous owner in Mid 2014.

its not super frustrating as lately i tend to just ignore it, but I am curious to know what could be causing it?

My previous Sr20det powered cars that were also stock with just bolt ons similar to this one, never smoked like this, only when under max load.

Any insight is much appreciated!
