The 138190033 Square Tip Rocker Arms come in a pack of two for the 196 clone engines. 

There are two style rocker arms: square tip and round tip. The square style becomes more prominent due to the stabilization over the round style rockers. It is not uncommon for the rocker arms to not be a true 1:1 ratio some times; they can be 1:1.05, 1:1.1, etc. This is important because it will change the running lift if it's checking for legality. Most rules allow grinding to make it a 1:1 ratio or compliment your cam for the maximum allowed running lift to fix this problem. 

These stainless steel pushrods are the OEM Replacement for 196cc 6.5hp GX200 Clones, including the Tillotson 196R/RS, Ducar 196, and Box Stock 196. These also fit the Predator 212 Non-Hemi Cylinder Heads.
