440source rockers now available
These are probably better for a more serious build but at this point I’m buying Harland Sharp rockers.
Detailed Description
For those who like the strength and simplicity of a bushed rocker setup without the more complex roller bearing, these are just the ticket. These feature fully pressurized oiling passages from the shaft to both the pushrod tip and the valve tip roller. As you can see in the pictures (click on the "view additional images" button for more detailed pictures) the quality on these is amazing. Made of high strength 17-4PH stainless, this complete kit includes EVERYTHING needed for a complete installation: 16 arms and two shafts, adjusters and 12 point locknuts for the arms, billet steel shaft holddowns with studs, washers and 12 point locknuts, 8 spacers to separate each pair of rockers, thin shims to set your rocker side clearance correctly, and EVEN a set of two checking pushrods so you can measure for the correct pushrod length. Please note: These rockers use standard BALL-BALL style pushrods, not the ball-cup style like most Aluminum bodied rocker arms use.
