What stainless valves should I buy?
Will ferrera 5000 be enough or Do I need 6000?
Anyone using Gaterman?

Experience with competition products house brand? They said made in Argentina and would work excellent with my combination.

Manley stainless valves are a nice replacement as well...

You'll be hard pressed to find a better stainless for the money than these valves. Include the "Pro Flow" feature and might even pick up a smidge of air.

Couldnt find rev in std size and 3/8” stem.
Yes know all Stainless valves are foreign Israel, india, china, Brazil, Argentina etc. Heard some of the best comes from Argentina? The competition products have a tempting price and they said price is low because of quantity they buy and good enough quality for my application.

I have also looked at Manley race flo and ferrea but since its budget the competition product valves caught my attention.

Some, if not all, Ferrea valves are made in Arg. I have used many sets of the 5000 series with no problems.

Yes ferrea is made in Argentina. Will 5000 serie work with what I plan thats the question or do I need 6000 series?

I think the 6000 series will withstand more heat, such as turbo/nitrous engines, but not 100% sure.

Contacted ferrea and usually they recomend 6000 for hyd rollers but with my pressures and 6500 rpm Max 5000 will work I was told.
