Different HP at different fuel pressure

I have a 1993 E350 w/7.3 IDI NA. I noticed that the valve covers have the International lable on them and it lists HP #s for different fuel pressures. 165 for one pressure and 185 for another. How do you know which one is for your engine?

Yours is the one that is punched. On your 1993, it's the 185 hp, the lower number is high altitude, IIRC.

Thanks for the reply guys. I'm new to the forum and diesels but I'm learning. I didn't know if the vans and pickups had different fuel pressures and HP's and if that was the difference. The van runs great, has 275,000 miles on it, and starts up with no problem even in the cold. It has a new IP, glow plugs, starter,rad., and return lines. No more leaks. No more slow/hard start. It does seem to idle a little rough, like a gas motor with a miss. It smokes very little but can only tell at night w/headlights behind you. What do you think about the miss?
