I think it's fairly clean,but is it normal to have a little bit of carbon lurking around inside?just seams like I blow air from side to side till the cows come home,and still not totally clean.

You might try sand blasting the inside, but I'd wanna get it pretty clean before I put it on an engine. Short of porting the entire insides there's not much you can do.

Have it bead blasted then use a flexable drexel tool and grind and polish ports.

Even though my Avanti engine is sporting a new Lionel Stone aluminum intake manifold, Michael Myer still used his drexel tool to polish out and remove any casting material and flashing from the intake ports.

You could take it to a machine shop and have it hot-tanked. Personally, I wouldn't sand/bead blast it internally. I would never feel that I've gotten every last little bit of the abrasive out of the manifold.

I personally don't recommend bead blasting any part on the intake system as I don't believe that all of the blasting media can be removed and the last thing your engine needs is glass bead media going into the cylinders. A thorough hot tank cleaning will remove the carbon inside of the manifold. Bud
