Rebuilding 902 heads

Stock or swirl polished stainless ?
$Low end or high end$ ?
Builder valves are cheap.
Kind of need to know what you're going to do with this engine ..as in the cam, and spring... the performance level you expect. Mancini,e bay, elgin, engine pro, ferrea, milodon, manley,pbm,Hughes, etc all have them.
I want to do a street/strip build or just a nice hot rod. I'm looking at a cam from Hughes that is a hydraulic flat tappet. It's 222/226 with 110 lobe separation. I don't really have specific power goal in mind right now. Maybe something between 300-400?
