Hello,
Has anyone had their aluminum heads plated? If so how did it hold up and where did you have it done.
Thanks
NelsonFebruary 22, 2017 at 3:31 pm #53426why would you plate the head if the cooling passages are functionnal ?

February 22, 2017 at 11:09 pm #53443There is a treatment called anodizing in which aluminum can be given various color treatments that seem to hold up very well. The object to be treated is made the anode
and the type of salt in the electrolyte determines the color. Along the same line as electroplating but a different process. Copper is above aluminum on electrochemical
scale so in a corrosive environment the aluminum would be sacrificed. That is not to
say it can not or is not done.

ie; cast in copper and polished,
on Johnson opposed twin race motors.
They may have been of some value,
but were not seen on these motors after the war .February 25, 2017 at 10:56 pm #53559Dupli-Color makes a Copper paint for a copper plate look.

LouisWhen anodized, wouldn’t the whole head be done? Would you want that on the inside of your head or water passages, to flake of sooner or later?
