I looked at my old Carl Munroe book and found the pic. Would like a little larger version but it did answer my question. Hard to see that small print. I'll have to explore FB.

From what I gathered, the largest O.E. valve was .490", and all of the repair kits are that size.

The v8 boost valve is .488, v6 was .475 and the small v6 and 4 bangers used the .460 boost valve. When a manufactor for a pressure regulator spring gives you pressures, they are basing them off the big boost valve. Each size smaller, is usually worth 20 psi.
