Coolant plugs?

[scaggsj]

I did a search but didnt find what I was looking for so I just put this out there knowing its been anwsered somewhere. I have an 87 7mge auto recently replaced headgasket and the stuff that goes with it. I didnt change the coolant plugs or #3 gasket. This is where Im starting to think I messed up. Cars been running fine but has been losing coolant, its been winter and the only smoke I see seems normal. (Im also running real rich you can smell it) So losing coolant at a slow pace didnt seem to be affecting power or causeing misses, then more recently the loss has gotten worse but still not bad but now its missing. I you get it above 1000 rpms it seems to run alright, again im having air fuel problems. No oil in coolant that I can see and no coolant getting in oil. How do I know if its the coolant plugs and how do if its the passages. I read something about that on one of cres posts.
