I noticed with my bushing kit that there were a lot of metal shavings/dust in the bolt holes. This was about 2 years ago. Now i have a ported lower 3400 manifold and there is aluminum dust/shavings in it! (i didnt buy the ported lower, it was sent with heads to match them up to what RSM did to the lower) Bushings are one thing, but an intake manifold is quite dangerous to have these kind of debris in it.
Has anyone else noticed this, or for that matter, even looked before bolting them down?
