3 row radiator, high flow t-stat housing and maybe a mod so you can set the aux electric fan to stay on all the time. Hood vents would also help with some heat issues.

I have a CFS 3 core radiator and a 180 degree T-stat in my 91 XJ. Keeps it cool!!!180-190 on the road and trail....sometimes still creeps up around 210 when on it hard spinning or pulling hills at highway speed. Soon as I get off of it or get back on level ground it goes right back down to 180-190 so, I guess that's just the nature of the beast.
