Hadn't heard ARP head studs would solve the issue. I thought it was due to a batch of RS engines getting Mustang headgaskets, which while each have similar engines the two versions have significant difference in the coolant passages between cylinders.The zr2 seat is height adjustable!
As for the ranger motor, it's the focus rs motor which blows head gaskets when you sneeze at it. Which isn't very good. Means you need to run arp heads as soon as you buy the truck.
