    not sure why a motorcycle shop would have technology that no one else has. Vapor blasting vs wet blasting to me seems to be the same thing.

    Mine looked perfectly clean as well- until I took it apart. I’d highly advise against skipping this step. It’s a 5 min job to remove the metal cover, 2 mins to reinstall, and rivets are $5. Sand blast grit will stick to any little spec of oil or sludge and eventually be released into the engine oil. The only way to verify it’s 100% clean is to remove the cover.

    They are one in the same. In my mind wet blasting seems more accurate but for some reason around here many shops use the vapor blasting term.

    I would blast an intake with any kind of abrasive material. Just one piece of grit left on or in it and the engine is ruined. I use liquid cleaners, brushes, and have used battery acid to get the white cast finish on a couple.

    I’ve done a bunch with zero problems. I always high pressure water blast them afterwards and always remove the heat shield underneath to ensure they are spotless. The wet blasting tends to leave less potential for grit as it tends to polish the finish vs. embed media

    my go to on factory cast parts is water (vapor) blasting. Parts come out stunningly like brand new. Here’s the same part glass beaded vs water blasted.

    Looking at the pictures that Rosster just posted which look most resembles what the manifold looked like when they were factory installed on these cars. When I received my kit car my manifold looked like the one on the left side with the flat aluminum look.
