My opinion is to go with Ferrea. Why? They make the best valvetrain components availible. Go ahead and do some more research. You will find some stories with Kibble but not with Ferrea. Their valves are truely a work of art. There are lots of people running kibble as well and that's probably why you read more stories about them but I have not heard one horror story with Ferrea.

I would stay with oem or a more expensive brand of after market like ferra or exaldine "not sure how its spelled I know thats not right" Ive seen 3 motors with kibby white valve explode because a valve broke.

yeah diffenatly go with ferrea, super nice valves, i have seen a few pictures of one bent, but never ever seen a broken ferrea. i run both kibble white, and ferrea in my motor, but i know when i rebuild the head, itll be all ferrea.

I've been running KB valves in my race bike for 2 years. The trick is to do maintenance.:devil: They def. hold up longer than OEM, but they probably aren't as good as the Ferrea.

The best available. Our offroad valve train components are the exact same quality as out 400+ hp sportbike parts.

We can also do custom valves and retainers.
