Horse shoe intake Heat soak?

Jeep Information

I just got some 4 hole injectors for the 4.0 . I can't decide on whether to just put them in or wait and do the 99+ horseshoe intake manifold swap with the injectors. I read that it lowers HP but increases fuel economy. I'm not worried about a few hp. But what I am worried about is the possibility of heat soak on the fuel rail. I haven't read anything suggesting that the YJ would have this problem but also can't find many people who have done the swap. I also plan to go with a larger throttle body at some point too. Any feedback would be awesome. Thanks
