Header wrap on crossover?

Which may help with underhood temps.

Lower temps would allow increased timing to create more ponies. But you wouldn't see lower under-hood temps. At all. So no ponies.

I wrapped my crossover because I had the stuff on-hand to do it --- it dropped the tb temp by about 20 degrees, not that it makes any difference mind you.
