 The 71 up have a thicker rib across the pushrod side and most people feel they're more rigid. ((mrmom9r of the XLFORUM http://xlforum.net/forums/showthread.php?t=1682099&highlight=splitting+rocker+box)) \\

+===== Rocker Box Gaskets =====
+-1969 Sportsters did not come factory with rocker box gaskets. \\
+Instead, a layer of silver paint was applied between each rocker box and head for sealing. \\
+In 1970, a gasket (17536-70) was introduced and retros back to 1957 models. The same gasket is used on each rocker box (2 required). \\
