i posted this thread becuase i was wondering what would be the best thing for a zc head with a 14b setup boosting 10-12 psi
like port and polish valve seating all that stuff.... i heard it was better to port not polish, i also heard the stock ports were best then i heard 3 angle was better than 5 angle i heard all sorts of differnt answers and i was just trying to figure out what the best head setup would be.....

 

valve job ported like any head
