95 Blazer S-10 w/4.3 Vortec

Was told #6 cylinder was misfiring. Replaced plugs, wires, cap, button, and coil. No change. Next replaced CPI. Still no change. Stumped. Anyone have any ideas what might be going on?

It was completly corroded clear back to the bend. You could hardly see where it started to turn into the "L"

What's the compression on #6 ? could have a burnt/sticking valve. Could possibly be a bad new plug also.
