I have 317s and am running 7.400" pushrods. We used a gauge to make sure we had they would work before installing them.

why would they differ? 5.7 heads are the same as 6.0 heads. I used the stock size ones.

I found spec for XER281HR @ 232/234 & .595/.598, is that what you have or if not what's the diff? Does the -12 mean 112LSA? If not what LSA is yours? What kinda boost you running? PM me if you can, not trying to steal the thread.
Most cams call for 7.4 push rods ( stock length ) unless you have milled the heads.

The deal with needing the longer p.r. With the ls6 cam is the smaller base circle

Different cams and different headgaskets will dictate different pushrods. Stock for stock they will use the same 7.400 pushrods as a stock 02 LS1.
But I am sure you will be getting a cam too............
