ferrea valve issue thread

Postby ST185pinjo » Tue Sep 03, 2013 8:00 am

There used to be an issue thread concerning Ferrea valves on here, but I can't find it.

Anybody knows where it is?

I have 2 fractured OEM valves. I want to replace them with Ferrea valves I have in my spare head.
I read on here there were problems with a batch of Ferrea valves. People who had them were upgraded to the competition ones.
I just want to know if I put good valves in. Taking the head off is not something you want to do twice. :wink:

It was on here some time ago, few years.

Can anybody help me?

Ferrea comp + never had the issue, only the 6000 series, and only Intake valves. Ferrea corrected the problem and now have a sticker on the box, mentioning upgraded alloy. Several years ago, they would trade out bad 6000's for a set of comp plus, but i dont know if that program is still active.

Ferrea etches the P/N on the stem of the valve above the keeper groove, so you can at least verify whether you have 6000, or comp plus.
