have you set your TPS to 0.70 vdc at closed position, it could be causing a lot of your idle issues??? just a thought
no, its been 0.55 after last time i adjust throttle plate
I also stumbled across a jewel of information regarding using this cam. Edelbrock suggest using their timing set due to some timing chains being machined to retard the cam. Retard cam timing would give lower vacuum, the look of a vacuum leak, weak off-idle power amoung other things.
so, got some time finaly, i change that bin, afrs are way off, and idle still not any better, also accelertion is too rich and car runs wery bad when wot...
so ill have to do something more but in the meantime, heres something for you...

The log is no good and nothing will run right with a Error Code 51 set. So clear the code, if it comes back you have a chip issue.
Your CEL at key on should come on, blink, then stay on till engine is started then go off.

I looked at the log anyway and yes it is pig rich most everywhere.
3/4 of that log was Open Loop so can't see BLM fueling adjustments, looks like it finally went closed loop when you started to drive.
Temp after a huge long warm up was only 165f, but then did get to 180s when driving, so I'd say way rich and keeping motor to cool at idle.
No idle left at end of log so can't help much there.

I'm looking at it now and so far pig rich still. Also an Async fueling bin... I hate Async fueling bins!
What's your fuel pressure?
Post up your bin that your using for this log.
