Manley or Ferrea valve keepers / locks

[spooled_u_1st]

Trying to decide between Manley or Ferrea valve keepers / locks. Is there much difference between the two?

I didn't even know they made them. Are you sure you're not talking about the retainers?

 

[spooled_u_1st]

Yes positive, I already have the ti retainers that came with my Super Tech Duals.

There's only few dollars difference in price on slowboy's website between the Manley's and Ferrea's.

Myself and everybody I know uses the factory pieces. I don't see the point in spending $90 on something that you can get for free and works very well. If you're going to get them, you can't go wrong with either one, they both make great products.

So you already have titanium's from ST but you're going to buy another set?

I have TI retainers but I'm looking at Manley or Ferrea valve keepers / locks.

He bought retainers, and wants to buy valve locks. They aren't the same thing, which is why I asked him to clarify that in my first post.

I'd not be surprised if they were not both made by the same company and just re-branded. There won't be any difference in performance between the two.

Nor will there be any measurable gain over stock. Back-to-back dyno runs will yield more variance than the gain you might make.

I know that there won't be any performance gains by using aftermarket valve locks. I was just worried about the stock ones failing at say 9,000 - 10,000 rpm's.

I got the Ferrea's. Great product, just about like everything they sell. Although you didn't mention what your using for valves and if your planning on using the stockers I would rather spend that money on ferrea valves.

I'm using stock keepers on BC TI retainers. Works fine.
