I would run a turbo with a larger turbine wheel and a/r. This will help keep EGTs under control with very long pulls. V mount with a vented hood sounds like a good idea. I'm not sure if its mentioned, but water injection would also be a good idea. If you are really worried about underhood temps, we offer a lot of stuff to combat that.
