Timing at idle causing too get hot fast

I have a 93 lx with a 306 9.8to 1 edelbrock performer heads cobra intake.on3 kit f cam moates with b.e.has a large alum. Radiator and cooling fans.this thing gets to 180 in less than 10 minutes of idle time.Iam re wrapping all the pipes.but I took a data log of it just idling from start to 180 to confirm guage accuracy.noticed air fuel was 14.5 to 14.9 and timing was at 30 deg the whole time would a little more timing and fuel at idle help combat this getting hot fast issue?it seems lean with not enough timing to me.but iam no tuner.

I'm missing something. Getting up to operating temperature quickly should be a good sign. What is your concern?

Not enough info, what dist are you using? any advance? like vacuum or the spout? total advance should not be more than 34. at idle if the timing is to far retarded, it will run hot, but 180 is not hot. If you have a dist with only mechanical advance then 15 -17 degrees at idle is good, but this also depends on the dist set up, and what total advance is. See what I mean, not enough info.

14.5 - 15.1 Idle/Cruise is perfectly normal. That's what my A9P did.

I've had factory vehicles wait to turn on cooling fans until 219F (NA Iron block, Alum heads, 10.0 compression, 87 Octane)...so the temp is fine.

180F in 10 mins is absolutely normal.

Not sure on the timing curve.

Nothing wrong with what you're describing. That AFR is perfectly fine. 30 degrees advance is a bit much for idle but probably won't hurt anything. I certainly wouldn't increase it.
