The se evo heads are not bad out of the box. I would at least cc the heads to ensure that the chamber volume is the same from front to rear. In that process remove the pc coating in the chamber as that is going to burn off any ways and will effect the cc reading. Mild clean up in the ports is always nice as well. Check the valve seals to make sure they are on correctly and tight.
