I bought a brand new type r clyinder head from acura a while back and it came with the valves, springs, retainers, and valve guides already installed. I then removed and sold them in favor for a new skunk2 pro-series valvetrain and installed them myself. My question is... Even tho the clyinder head is brand new and i'm gessing the valve seats are perfect comming from acura... Will I need a valve job?

 

yes

 

Need = no
More power = yes

 

If the VJ is going to be done on a Newen, chances are good you can improve. If not a Newen then go with what Honda gives you.
