Well that's a good question. There are a couple of ways to clean the combusting chamber without taking the heads off. You can go to your local auto parts store and ask for a can of combustion chamber cleaner. Follow the instructions and you are all set.
There is of course the do-it-yourself, aka home brew method that consists of nothing more than spraying regular tap water into the intake manifold. The later one is a little tricky and requires some finesse. Either way the results are the same and they both works just fine. The idea behind either method is to steam clean the engine. The water spray is an old mechanics trick that’s been used for decades. I’ve tried both over the years, first the can from the store, then just water and they both work great.
If you are using the store bought product and follow the instructions, then there is no chance of hydro locking the engine. If you don’t know what you are doing the do-it-yourself way, you can, not easily but you can hydro lock a cylinder or two. Hydro locking the engine will for sure result in breaking or bending something.
I would suggest you to go with the first method!

I've used the water down the intake method (it's worth mentioning to Murphy that one does this with the engine running). There was a LOT of crud in that old, dirty running engine. What will that do a catalytic converter?
Is the store bought stuff any less likely to clog a cat, to your knowledge?

Good point, I forgot to mention the obvious. The engine needs to be running while either method is being applied!
The carbon that comes off the piston tops will simply burn up in the cat.
