A lot of guys are using 'silver head nuts' on their flatheads.
Does anyone know the typical way this is done? Zinc? Stainless?

Just plain zinc head nuts? Will they rust? Is the metal 'grade' a concern?

From what I've found, stainless is a bit shiny, and I'm not sure the metal 'grade' is high enough since stainless is typically softer.

Originally, no head nut washers were used, but I see some guys using washers, presumably to give a more accurate torque and to prevent the flathead seats from chipping?

Also, with some suppliers, it's unclear whether the bottom of the nut is chamfered to help prevent the nut from digging into the head. Got any recommendations?

FYI, this is for a 59AB engine in a stock 1935 pickup.

Thanks for your time.
