Welcome to AF
That sounds like a nice car!
I would be interested to know of the mods you have done to the slant six.
Given this engine has a relatively long stroke and somewhat small valves, I thought the only way to get 445 hp is by using a hand grenade..........
As for chrome......... if the blemishes cannot be polished out, ideally the piece must be stripped, prepared and re-plated, which is a relatively expensive process.
