Yes , thank you Rocket . Yeah I'm familiar with the crane small block rocker arms which is what I was told these were. Tell me the middle picture as the post appears to me in your msg. the rocker arm on the right hand side bushed . I can see the bushing in it with the arched rib above the arm , what make is that?

The rocker on the right is the picture in posts #14 & 32 is a Mopar Performance W2 exhaust rocker arm. The rocker is much thicker in the body and has plenty of meat to add the bushing.
