Intake Leaking Oil

I chased the head bolt holes and cleaned the bolts. Everything is ok.
Removed the roll pins.
I don't have any gaskets yet but I used some pieces of .060 thick material to get the intake up off the end rail walls. Measuring from the top of the wall to the bottom of the intake it was:
Right front- .052
Left front-.028
Right rear-.042
Left rear-.024
It does has a very little rock back and forth. I also noticed that when I took the intake off I loosened all the left side bolts first and the right side bolts were loose. So the intake shifted.
If I'm thinking about this right, that means the top of the intake port has more clearance
than the bottom, but it's leaking at the bottom of the port and not the top. Seem's like it would be the other way around.
