yup, that's the valves I looked at, Manyley makes a nice undercut valve, Weighed some of the Ferrara valves I had around here from Ford engines,, surprised how heavy they were.. Just thinking the old lighter valve train lives longer thing....

Here was an old Smokey Unik trick ! It's in the How to "Hot Rod Small Block Chevs" book, what you did was get the standard pressed rocker arm and lighten it a bit by making up a former as detailed in the book, put the rocker arm in and grind down the sides. The whole idea of the former was to lighten the rockers to a uniform weight and in such a way that it did not compromise rocker strength. So with your lighter valves rockers and retainers there was whole overall reciprocating mass drop over the whole valve train. I suppose it is just knocking off weight here and there that the whole weight saving adds up.

Kinda like the old deal that it's hard to find a place to take 100 pounds off a car, but not too hard to find 100 places to take off a pound, i guess....
