I think since it's an R its worth replacing the part(s) rather than adding nasty goop to the system. I had some "OK" experiences with stop leak until it caused a blockage in a 1.8T VW and cracked the head. Its anecdotal experience of course, but I think its worth noting. I'm not a major fan of kittens but if I can save a kitten and a head replacement at the same time, I'll go for it

Thank you for the input. The reason I am wary is because of an issue I just went through with my other car. Previous owner had the motor rebuilt but the machine shop took too much material off of the head and the block as well as leaving the wrong RA finish. We went to fire up the car after the new engine was put in, not knowing this prior, and it began leaking oil. I was lucky that I had an identical engine I just removed to have more machine work done to start all over.
Since I know this head has been removed, I am afraid of the same thing happening again(taking it apart to find out nothing can be done with it.) I do not have another engine at my disposal and do not currently have the funds to buy another one and have that one rebuilt. I also wouldn't trust any motor I bought from someone to be ready to drop in and run. I would basically want to rebuild the whole thing and start new.
I guess at this point I will at least hold off on the stop leak treatment and flush the coolant another time or two then see where I am. It seems to be what I have read that it sometimes takes a couple of times to get all the silt and crud out of the cooling system.
