Biggest source of radiant heat by far will be the exhaust, so I’d look at ceramic coating or wrapping the manifolds (at least). Make the cooling system as efficient as you can (modern radiator, shrouded electric puller fans, high-flow water pump etc), carb spacer, good oil cooler, heat shielding/sleeving fuel lines, reflective bonnet insulation, maybe even removing the bonnet seal etc.
