Machined from aluminum, these acorn nuts will replicate those found on the flat heads of yesteryear. They are in the form of a bolt head with a short stem. Drill locating hole and glue in place. Domes have been lightly polished for minimum finishing if any. To find the sizes you need, divide the actual size of the Acorn Nut Hex (Heads - .800" / Intake and Exhaust manifold - .600") by the scale you're working in.

* NOTE: You will require 2 - packages when doing both heads of one engine. (48 - pcs)
