Valve lengths

Which valves would you recommend for NZ casting EQ heads? Assuming both work, are the liberty much more expensive than the LS valves?

You would probably have to go to their site and research the valve lengths and diameter. I’ve never worked on that particular head. I just started getting these as a cheaper option for my customers but after seeing the difference in flow I may be switching over to them. The pro series are more expensive but not that much more per set.
