Hard to say age on mine, as said procured engine w heads on. United Engines Specialists has a Flathead only dept so assuming they have heads they’ve bought in bulk on the shelf who knows how old. I’d think ur’s marked 425 indicate sequentially a more recent run? Scale the reach on the N5C’s u have. If they’re actually 3/4” as spec indicates it’s the reason they’re not fitting mine. Calculating mine require 5/8” reach which Don’t seem to exist?
