1.38 Ratio Rocker arms
These are advertised as 1.4 rockers, but they measure out closer to 1.36-1.38. Most 1.4 rockers are closer to 1.5, and you can get into valve spring trouble real quick. .
Comes with 8 rockers, solid shafts, blocks, and shims.
As with ANY custom cam/head/rocker combo, these will also need correctly sorted rocker geometry, and custom length push rods.
