318 diagnosis

UPDATE:
i swapped out my performer intake with an LD4B and thinner gaskets (.030) with no change in smoking issue. I confirmed oil was being pulled up from the valley into the bottom of the intake ports.(pics) I used Gasketcinch on gasket to head side and RTV on intake to gasket side around ports (smear) with no change.
When i laid manifold down on bare heads I could not see any gaps and bolt holes lined up but i didn't look very hard at hole alignment with gasket on. All bolts went in w/o much trouble.
Doing more reading, someone mentioned their machinist said to use thicker gaskets (.094?). I guess i'm willing to try that before pulling heads.

I really think head machinist screwed these up as i also had stem height issues.
I have a set of 302 heads done by same guy but ideally shouldn't use them with whiplash cam.(raises compression too high)
I have another set of 676 heads of unknown mileage/machining.
