If you are considering, the only two I'd even think of are the u-shaped hose between the t-stat and WP and the return hose from the top radiator hose over to the coolant reservoir. If you do the hose from the head to the T-stat, just get the aluminum hose bib part on e-bay and keep the hose and just change out the bib.
