I just acquired a set, what appears to be the second version/casting, that were produced around the 1999-2002 timeframe. Yep, the catalog does say that they use the production valvetrain. I mocked up one head and the stamped steel rocker & non-adj. pushrod pieces fit perfectly to the lifters. Not that I'd use them. No interference at the cylinder head-to-pushrod passthru.

It is the "Max Wedge" versions that came later that need a special offset rocker. NOT all Stage VI'ers.
