So, I fired up the engine and all the clacking sound is gone. Yeah!

Here's a video of it after:

It sounds nice to me but if you all can hear any other issues, please let me know.

Great Job! Time for a cruise! The only thing I see is the spark plugs should be pulled away from the headers so you don't run into a ignition problems. They sell protective socks that slip over the wires
Thanks! Yes, agree! Darn thing is I have my dash all apart working another issue!

I just ordered a pair of socks for my spark plug wires. Should get them Tuesday.

Thanks for the idea

Earls, they also make collector gaskets.
Thanks, I was looking at copper gaskets suggested by @fishslayer143; however, when I was looking I saw "Percy's High Performance Seal-4-Good Header Flange Gasket" and used those. Or at least just the passenger side that was leaking. Hey, if they "seal-4-good", they have to be good right.

Well, if these fail, then I'll take a look at these too.

I agree. This is the known as 'EOIC' method (Exhaust Opening/Intake Closing). It's by far the easiest way to adjust valves in my opinion.
