so I see 2.5 oil pan with 2.5 oil pickup can help in that. does any 2.5 oil pan suit my needs? even 2.5 NA engine pan/pickup?
I have stock headers also
You have a PCV issue by the sounds of it. As stated, no pan will solve this. There are some good threads going on IWSTI right now. Go take a peek

Not nearly as much as most assume. It takes much less lateral force to fill the head vs slosh out of one. A long enough corner will fill the outer head and empty the pan without sloshing out any oil. This is really easy to see for anyone that has an engine/stand. Tip it and you can easily see how much force makes oil pool where and first.
One of these days I'm going to get off my butt and do a full on technical Suby oiling system write-up
