Tired of DIY!

When I pulled the engine, I didn't see any real evidence the rear main was leaking...and then there's the oil on the starter...weird.
I know the cam plug was leaking. I put the correct one in and slathered it in Ultra-Grey Permatex, and peened the center. I doubt it is leaking now.

The carb is a Proform 750 with maybe 1000 mi on it.
I am running a Lokar throttle cable and kickdown. I don't think this setup puts any undue stress on the throttle shaft.
Even with a stethescope , nothing is conclusive on the carb or valvetrain.
It's not one lobe louder than the others, and I measured a bunch of them while I was in the engine.

YR- I talked to B3 but he was swamped with Carlisle and never got back to me.

I didn't get my AFR meter in yet, and haven't pulled plugs yet. So drained today I actually left work early, which is unusual, just trying to get my thoughts together to attack it later this week.
Thanks guys!
I appreciate the suggestions and empathy.
After the head porting, I was excited and thought yesterday would be badass, not more issues, it was a hard hit.
