Changing starter

I am having the same hot soak problem, have to wait 10 min after a run for the car/starter cool down. Wrapped the starter which didn't help but haven't tried wrapping the TTI 2" header tubes around the starter.

Any suggestions on the smallest starter that can get the job done on a 10.5:1 motor? Currently using s Mopar mini starter from a V8 Dakota but was hoping to have a smaller started that would provide better clearance.
