Yella Terra YT6321 Platinum Rocker Arm Kit for Big Block Ford

I've been using the Yella Terra YT6321 rockers for about the last 15 years with great results. They work well with a solid roller and they are a cool solution if you're running a hydraulic roller in a big Ford or Cleveland where the pushrod is out of plane. Since they bolt down solidly to the head they resist the side to side movement that happens when you use a stud mount rocker in that application.Very heavy duty with very strong trunions, bearings and body.
