The Hemi Conversion roller rockers are almost too pretty to hide. Hemi scholars will note that the pretty, red-anodized rocker-shaft stands position the exhaust rocker shafts 1/2 inch closer to the engine centerline than regular 426 Hemi stands. This is done to straighten the exhaust pushrod angle and get them away from the confines of the wedge block's tighter lifter valley. The cast stainless exhaust rocker arms are 1/2 inch longer than stock to compensate. The valve angles and 175cc chamber volumes are identical to stock Chrysler 426 Hemi castings.
