Sandblast and Cerakote C series satin Nickel. I recently did this as it resists fuel staining and learned this from the Fordbarn when bored and stroked mentioned his uses it on Carburetors. The C series is air dry and requires no hardener.
As mentioned Tumbling or as the Vette guys call it "reskinning" the cast aluminum pieces is the best looking method. There is one guy all the vette guys use for their Fuel injection parts. he qouted me $600 to do a pair of heads and a intake. I was just too cheap to pay that..
The Cerakote spray easy I spray it out of a $5 harbor freight gun. The C series does not need to be cured and is ready to spray. You need to keep it in a air tight container when done or it will go bad, and only spray a light coat.
Satin Nickel seems to be my favorite color for aluminum and Glacier Black for Model a carburetors and V8 carburetor bases

Reskinning or a coating is the only way to seal up the pores. Blasting cases the pores to bhe open and greasy finger prints and fuel stains easily.

Thank you. I also have one of those cheap HF guns. I'm going to give it a go. How much did it take to do the heads and intake? A pint?
Besides blasting, any other "special" prep before painting?

NOOOO... the 4oz tester botle they sell was enough to do 7 carburetors 2 heads and 2 intakes. A pint would go a long ways.
The HF touchup gun works well as they stuff sprays thin. WEAR A RESPERATOR, this is some nasty stuff the C series isnt too bad but the H series that has to be oven cured is some nasty stuff

Tim be sure you wrap tape around the lid after you use it or it will go bad since it is ready to spray
