Aluminum intake manifold restoration/reconditioning

[68camaroz28]

It does look better the last two engine pics as it did seem too silvery and shiny looking for what IMO it should look like. Still a nice step up from what it did look like I'm sure.

Too silvery and shiny in my opinion as well. The repro valve covers are very evident with the wavy ends on them.

I've cleaned several that are fairly rare and never painted them or blasted them. Mostly just strong detergents and gray scotchbrite then steel wool. The steel wool will provide a bit of sheen, so use with caution. They take on the look more akin to the alum. thermostat housings, more of a dull grey, vs. the silvery look. That, to me anyway, is accurate. No protectant on the eddy, boeshield on the winters manifold.
