Still haven't pulled the spark plugs, but after driving it around for a couple of days, there are no leaks anymore.

So, no more coolant leaks, and I now have cabin heat. Those were my two symptoms and I can totally see how that looks like an HG issue, but im feeling pretty good that I've fixed the problem.

Thanks again to everyone for your input, couldn't have done it without you.

I'll still be pulling the plugs and looking for coolant. I might consider doing a leak down test either way, but I've never done one before so I'm not too sure of the ins and outs. I'll watch a few videos and read a little and make a decision.

I pulled the plugs today and put a borescope down each one. These are the pictures I got. None of them looked like what I would expect them to look like if coolant was leaking through. No wetness or cleanness. Keep in mind, this engine has 220,000 miles on it. I did notice that the plugs were single ground and not double as the manufacturer recommends. I'll be replacing them with double ground plugs (unless advised otherwise).

Here are the pictures, what do you think?:

When I inspected my cylinders/plugs on my engine that had a bad HG, I bore scoped them and they all looked pretty much the same. The leak down test is how I knew for sure I had a blown HG on the #3 cylinder.

I would just top off your coolant and keep a close eye on your coolant level now that you have your leaks fixed. If your not having any other symptoms of a bad HG, it's probably fine.
