Wow, a few questions, then. About what year might this have been? Are the velocity nuts SS or were those Ti too? Would a Ti valve be more or less resistant to scratching?
If you scratch a SS Classic valve, such as what you see a lot around the air inlet where it's been gouged with a wrench, the scratches are yellow/gold in color. Would a Ti valve not show the same thing?
