Need some experienced guys to chime in and help me choose a descent valvetrain. Im debating on ferrea or supertech but I've seen some bad experiences happen with the supertech valves but heard good things about their springs and retainers. Also is anybody running the ferrea 5000 or 6000 valves. Which is better? Might use the combo of ferrea valves and st springs? Thanks and your input is much appreciated.

 

Power goals? motor? oem valves can support most setups

 

Goal is around 700whp. Ls/vtec with b16 head

 

If you're willing to spend me the money for Ferrea springs and 6000 series valves that's the way to go. But a lot of people are also have success with supertech Valvetrain. All depends if you want to spend the extra money.

 

I just decided to go with the 6000 series valves and super tech springs. Hopefully this combo will work good for me.

 

I believe bisi informed me the fresh oem valves will handle 500 or so whp. Just fyi for others looking for them. Im not looking for the same power range but had a hard time locating threads discussing what to do about valve train. good luck with the build bud!
