Upgrade the H/E when you do the install. You can route the lines a better way then how KB depics them to take restriction out of the system. Take the fittings out of the back of the manifold and off the H/E resevoir and put permatex hi temp thread sealer on them. I would also make sure to add a bottle of water wetter to the system and ad a 170 degree T stat to help with coolant temps. Nice pickup BTW.
