(I'm going under the assumption that AFR uses the same core before CNC'ing the 180/195 heads.)

The hyd roller engines have a stock length of 7.200" The flat tappet cams came with a 7.800" length. If you are running the stock ZZ4 cam, there is a good chance you will need a 7.200" pushrod. Small base circle cams create the need more than anything for shorter pushrods. And most mild cams don't have a greatly reduced base circle

DO NOT rely on what someone else is running. Measure then buy what your combination calls for.
