If the exhaust valve is not working (for whatever reason) that would contribute to the carbon fouled plugs. It would be easy to back off the #8 rocker arm (when the intake valve is staring to close) in order to see if the push rod is straight.

If it's bent, well that would be an easy fix. But, usually there is an underlying reason the push rod is bent. In my case (early years) it was due to missing 3rd gear

You could say I broke some parts while honing my craft
