This is all a matter of personal taste, but I'm having a little trouble understanding the apparent contradiction between wanting the original 1962 paint codes so you can get the exterior to look exactly, precisely correct…
…and trying to come up with a nonstandard underhood paint arrangement. :shrug:
Again, it's a matter of personal taste (and they do make high-heat clear coats if that's what you really want to do)...but what means "too red"? In stock configuration, you've got the black air cleaner, the black water pump pulley and fan, the black alternator brackets, and the black engine mount and transmission brace brackets to balance things out.
On the Australian "Pacer" (high performance) Valiants, they really went wild under the hood...yellow air cleaner, blue valve cover, orange block, etc.
