The 82-84 heads are not the E5TE's that are in the 85. They do not flow well so the switch is worthwhile, just change the valvesprings as noted earlier. Do check the piston to valve clearance, it should be okay, the pistons are not the same as the 86 5.0. The pistons in my stock 82 motor also had valve reliefs so I'm pretty sure you'll be fine.
