Denso Starter Heat Soak?

Has anyone had problems with denso starters and heat soak causing them to not to start? I'm routing my exhaust fairly close under my starter and don't know if this will cause me problems. I plan on using heat tape from my collector back because I'm running real close to my rack and pinion on the other side. 48 Plymouth with 360 Magnum transplant.Thanks, any advice will be appreciated.
