Best carbon cleaning method?

[KDMCozy]

Hey guys, new stinger owner here. I bought mine with just under 48k miles on it and I plan to carbon clean it at the same time I put my catch can in which should be at around 50k miles. I’m torn between walnut blasting and chemical carbon cleaning. Can anyone help me decide? Which one cleans the engine better, is better for the engine itself, etc.
thanks in advance!

You are not cleaning the engine. Only intake valves. Walnut blasting is much faster method, and probably give you little bit better results. I clean mine with chemicals, because i don't have power in my condo garage.
