I remember doing this to my LLT way back in the day. Definitely a huge improvement.
I'd also like to point out that I was using a catch can the whole time and still ended up with some valve coking. It was a lot of manual labor on the LLT as the intake valves are positioned differently and I couldn't get a good angle to blast with walnut shells. For anyone with an LFX, that $50 for the blaster is a great idea!
