So the OEM is a bit longer.

The ends description are included in the spec and can be found further in the ELGIN CATALOG (See Attached)

You really won't know until you install (one cyl), lash and then check valve-train geometry (IMO).

Maybe call TECH?

OK, thanks for that info. Using tape measure and hand held measuring, I'm showing about 8 - 9/32" for one of my new rods, so that more or less jibes with what KULTULZ says Elgin claims the PR-71 rod length is. Now my questions are:
-Why is the pic Elgin shows of the PR-71 rod different than what mine is?
- Why is my original rod shorter than the Elgin rod, not longer?


I might just call Elgin, or email them a pic of my rods to see if I got the correct ones.


OR...I might just keep the straightened out original rods in the car, since I'm not seeing any overt negative consequences of running them.
