Good. It is probably just a cooked wire/boot. It does not take long to get the header glowing orange right where it attaches to the head with retarted timing. It is thin material and the exhaust valve is open during plug firing even if timing is just a little retarted. A couple miles will do it. Spark takes the path of least resistance. The plug is a resistor with a gap. Arc from the boot to the header is the path of least resistance.

If your firing order is right
the other cyls are getting fuel so your # 8 is too
Check your valves to see that they arent hanging open.
Adjust them too tight? Other issue? Rockers go all the way up and down like the others? Fire it up momentarily without the valve cover on and see what its doing.
If the valves are hanging open youll have a dead cyl

Small update here.
I've checked compression, THERE IS compression on cyl #8 so there should be no problems with valves. I've noticed that changing A/F on that side helps (plugs are very white so maybe its too lean). But why only cyl #8 not working?
