I would use the search fuction but it doesn't work so please don't slam me. I am just wondering what after market valves are people on this board using or if they heard anything about specific valves ie Ferrea or Crower. Those are the 2 that I am really looking at. Plan on buying monday so I am waiting on responses from you guys and girls to make my decision. Any info good or bad I would appreciate.
Ferreas are more expensive compared to the crowers but the difference isn't enough to worry me.

 

I have Ferrea and havent had a problem with them. Havent had the motor apart after the build so i couldnt really inspect them, but nontheless ive had no problems so far.
I would just suggest if your going to do valves then you might as well go oversized, price doesnt change at all.

 

Don't you have to do headwork to support biger valves

 

If you go with .5mm oversized valves, then you dont have to open up the valve reliefs in the head. 1mm or larger you'll have to have them opened up. If you are going with larger valves, the entire head has to be a system to take advantage of the larger valve. Larger throttle body, port and polish, higher lift cams, etc will so the real benefit of the larger valve.
