Lets talk valves,
Well you can have affordable or you can have good, but many times you cant have both. But here are some brands to consider tier 1 budget....... SBi , Elgin, and Qualcast. next tier 2 better....... Si , REV and Engine Tech. It all depends on the application size budget and goal . In the tier 1, I"d probably go with SBi , tier 2 go with Si or REV . If you want something better go with Victory or Xceldyne .I agree with KCS , Ferrea is a good valve , but a little heavy. I have not used the WS6 store valves but from the specs and pics look like a good piece I like there exhaust valve it has a extra thick margin as iirc Oh and I do not like Manley ,go with anyone I list before them jmho
