Re: Rebuilt Flathead Problems.
Valve spring height determines the valve seat pressure. Say you want 50 lbs of seat pressure, you would have to measure what spring height gives you the 50 lbs. Then the spring height needs to be set to that height on the valves. The install height is measured on the valve assembly without the spring and then shims added to archive the install height desired. I sure this is totally in-clear! You should be able to find a step by step procedure online.
