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

 

I wonder how much turned down ls3 valves cost. OEM valves, and light. Win win.

 

Yes TEA turns them down to 2.05 all the time , but don't think I would go smaller. than that cost $34 @ summit .racing plus turn down and back cut.

 

I had wondered what the minimum size was. Thanks for infos
