Stripping powder coat

I bought these valve covers from a member thinking they were painted black. To my surprise, they were powder coated. I spoke to a local powder coater, and he had a guy that has a proprietary process to remove it. I'd call a local powder coater. Here are the images fore and aft.

Not sure what a proprietary method might be but it's my understanding there are basically three ways to remove PC.

1. Chemical (acetone, MEK etc)
2. Mechanical (abrasive media)
3. Heat (It's baked on, it can be baked off).

Where I worked as a teenager they had an oven to clean blocks, heads etc. It got to 800 deg and anything non metal was ash. I have a blast cabinet but I'm worried about being too aggressive and damaging the intake itself. If I can get away with chemically stripping it, that's great.

At the end of the day I'm fine having someone do it, but so far I've not gotten a call back.
