Ok so yesterday i got some time to finally work on the car. #1 I installed a new epoxy filled Flamethrower coil. #2 I took out the air screws and cleaned them. blew out the opening in the carb and reinstalled to factory one and a half turns. Then cleaned the inside and exterior of the carb with spray cleaner. #3 Switched the distrubter vacume hose from the left side of the carb to the right just for kicks. #4 Replaced the FRAM oval air grabber filter with a stock paper filter. One thing i noticed was my indash tach started reading correctly again. I know this as for a long time it read about 500RPM high. Now it is exactly on the money with my new Sun tach i just installed. I drove it all over last night and it still popped slighty only now when in 4th gear on the freeway under 2000 RPM but it's 75% better i would say. When i drove it on the surface streets it had no more issues at all as i would not stay in the lower RPM range for any legenth of time. So i'm pretty happy things are almost cleared up. I think the next thing is to take the carb apart and look at the main jets for any issues. Thanks for all the good ideas and advice.

Try this very easy trick. Get the car running with airfilter off, rev up engine and choke it while revving with the choke or your hand (It may hurt your hand alittle if your doing it right). Me and my buddy used to call this giving the carb a BLOWJOB, it has cured many driving issues than any other trick out there. It causes an extreme vacuum in the carb and if anything is lodged it will free the dirt out.

Just an update as to how things turned out with the popping issues i was having. I took the roadrunner to my buddies shop and he spent some time tuning the Edelbrock 650 Thunder Carb. After a couple of times replacing jets he told me had to turn down a pair of jets on a lathe to get the perfect size for my application. The car runs awesome now, better then it ever has before. So in the end it was a very lean condition that was causing all the issues. Thanks for all the advice and help people.  Stu

Maybe that explains why when I took the Eddy off of mine and put on the 650 Holley the popping only went away after I jetted up the primaries.  I like the Eddy carb but I'm just not as up on tuning them as I am the Holley.

IMO there's a whole bunch of carbs running lean nowadays causing all kinds of problems, like overheating, running poorly, burning off header coatings and more.
10% ethanol needs to jetted up over straight gas, but lot's don't believe it because of some electronic gismo that is not accurate on our old cars and motors.
Edlebrock 1406 carbs are way lean right from the factory, you need to jet those up before even putting it on your motor.
My opinion...

I too, wanted to say lean. Didn't want to get laughed at. One of the biggest clues was your header coatings. The guys said coatings last unless there was something improper done, such as breaking in a new engine and letting it run to hot that the coating would not fail. This would be the result of running lean. You would have very high exhaust temps. This is most likely what caused your header coating to fail, also. Good luck, Stu.

What gismo are we speaking of here?
I have read quite a few posts where folks are complaining about overheating. I suggest to jet it up to see if it will help cooling. And folks tell me that's not it because they have one of these web page
Well just because it says one thing doesn't mean you shouldn't try to jet it up anyway and see how it runs.
IMO that tool is not a bad tool but I would not let it keep me from tuning my car and see how it does no matter what reads. Plus I think the sensor can get tainted and give false readings. I may be all wrong...
I do know one thing for sure, richer is cooler.
And I think some folks are tuned for the race track and not the street.

You know that's interssting as I just bought a used LM1 so I could stop guessing where I'm at. thank you for the timely info as I will get it in the recommended range then experimant going a bit richer to see what develops but as is I have no idea if I am way too lean or way too rich. I will call Innovate & ask them if they think it should be sent in to be recalibrated
