Crane Cam ID numbers

After many trials and tribulations, I have pulled my camshaft to, hopefully, find some ID numbers on it so I can replace a broken valve spring with the correct one.

It is a Crane camshaft and the numbers look like HMV-278-2-NC. I looked it up on Crane's website and found a close match:
part number 363801
grind number H-278-2(replaces HMV-278-2)

What I am wondering is - Are the specs the same? Did they just change the grind number? I have been trying all afternoon to call Crane Tech Support to verify the specs, but keep getting a busy signal or "all circuits are busy" recording.

The numbers 36 25 90 are also stamped on the end. Any idea what these 3 numbers mean?

That's what I though, but I wanted to be sure. I finally got through to Crane -- turns out they were upgrading their phone systems. specs are identical to the new part number. Curiously, though, the RPM range for my cam is 300 - 500 RPM higher than the repacement cam.

A couple of questions I forgot to ask the guy at Crane, though:

1) when I put the cam back in, should I use assembly lube, like I would for a new cam? I would think so, but want to be sure.

2) Do I need to "break-in" the cam? I will be putting the original lifters, push rods, and rocker arms back on. I wouldn't think I would NEED to, but it wouldn't hurt -- better safe, than sorry, right?


Thanks

Thanks for the advice. I have all the lifters, rods, etc in 16 labeled ziploc bags to keep them all straight.

Now I just hope I can put it all back together right
