Denso Starter Heat Soak?

No concrete knowledge on the origin of "Tuff Stuff" branded starters—odds are if it was sold as brand new, it is Chinese.

My '89 D100 with 318 had a heat shield on its Denso starter as original equipment. Pretty sure most/all of the 3.9, 5.2, 5.9 trucks and vans with this starter, and probably the M-bodies with this starter, had the shield.
