Thanks, Mike and Bob. It is such a small thing but can be a big trouble
maker if not addressed. I have plenty of time to deal with it so I will
stop by a machine shop to see if it can be easily replaced.
Except this freeze plug, the AMC heads look OK to me. But of course the
look can be deceiving. I know I will be gambling in using a pair of used
heads. I will use these AMC heads only if my OEM heads are found to be
worse. I have not dropped the engine yet. I need to make a decision
between pouring a lot of money or very little for the 84. It's not a
camper and it's old. But I do like it so I may still want it fixed.
