Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

So I just measured my pushrods with an adjuster tool, and at zero lash (I lengthened the tool until it contacted the rocker, but was still able to spin with some resistance) and it measured out to 6.760", so I ordered 6.800" pushrods, both because it's a round number and it gives me .040" of preload, which seems like it's right in the middle for preload for what my engine is built for. I'm hoping this will be the reason why my valve train is all noisy, and once I get the new rods in hopefully Thursday, I'm going to drive around, see if the current carb tune will still work, and then read the plugs and continue tuning from there.

I'm not sure if any of you guys have messed with ChatGPT at all, but I've been communicating with it about my current engine build, specs, etc and asking it for advice and comparing it to what was said in this forum. (I gave it the same situation/questions that I posted here, and it actually gave almost the same answer), and I'm very impressed with the responses its providing me. I've actually been experimenting with its responses to increasing my fuel economy, and while obviously valve hang due to too long of pushrods is the number one thing its saying to fix to gain mpg, its also been saying that I want to be closer to a .060" TSR, and potentially a 64PMJ, but it thinks a 65PMJ would be better, which is actually very close to what has been said here. Of course the number one way of figuring out what jets and restrictors I need is to read the plugs, but I figured I'd share how interesting it is that ChatGPT seems to have the ability to read forum posts and such as well as just simple google searches as it has answers that you can't find on the surface of google.
