But Slowcrash, isn't the thicker head gasket compensating for removing material from the head or block. In effect, the volume of the combustion chamber shouldn't change, that much. Right?

Trying to wrap my head around this. I maybe wrong.

You are correct and the change is minor and likely not enough to affect combustion significantly with the specs OP plans to go with. Just throwing it out there that you can't just mill the head to your hearts content and compensate for deck height with just the head gasket.

The limit it the manual does not account for the ongoing timing chain issue, where the current chain geo is near the limit.

my head has been milled twice, and I have no idea by how much.

Regarding the accelerated wear of the chain and sprockets, will there be any warnings signs I should look out for (noises) before the chain gives up and my engine is a total loss?

The signature rapid clicking is the first indicator of a loose chain. It is easy to hear and sounds like no other noise.

i would think a loose chain would sound similar to the TCT rattle, is this not correct?

Would they sound similar? car in bicycle spokes, increasing speed with throttle...etc.?

The TCT rattle sound is actually caused by the chain being loose. The TCT itself does not make any noise.

You are correct, the sounds are one in the same. Card-in-spokes tct rattle is a loose chain.
