Are Screamin Eagle Heads ported and polished?

 

Ported yes, polished not. Depending on the type of s/e heads they have different amount of cc's and different size valve as well. They do flow o.k. but in my opinion always have the heads ported for the cams being used.

 

There ported but to get them flowing nicely you will still need them for be ported some more and polished.
