I am stuck beetween what valves to use in my Evo 9 head that is going on a 10.5 cr 2.4L setup with kiggly beehives and Evo 9 tomei 280 cams. Wiseco 1400/MAP ultimate. Turbo is a 6765. Goal is to make 900 someday.
I've been looking into ferrea 6000 SS series valves. People also tell me to use supertech or Manley valves.

What do you hight hp guys use?
Thanks

 

Ferrea competition plus, 1mm over SS valves are the best valve I have seen that is off the self. I believe the part number is F1452P/F1454P. An extremely high quality valve.

 

Would you recommend a vendor or aonline store that i can get a good deal on them?
Thanks
