It was a common practice at one time. VW Derrington would copperise your cylinder head for 25 shillings. Copperising was supposed to improve the heat flow and prevent local hotspots. Whether it worked or not I’m not so sure. Current theory is you get more power out of an iron head because the heat flow is slower. Copper would make it worse, maybe?
