| RE: Shouldn't lifter adjustments have locking nuts? |

| The factory adjustable rockers (besides a different pushrod end) use an interference thread with an x in-oz minimum torque value, I can't lay my hands on right now, below which you replace the screw or screw and rocker. They work fine until you're talking more spring pressures than the overhung end rockers can handle without shaft deflection causing the rocker's solid bushing to gall the shaft and literally cut it off, KURPLOP goes your rocker arm. Harland Sharpe makes an excellent roller rocker, TRW used to have a kit (I'm talking 15-20 years ago), but, you still have the overhung, or cantilevered rockers at each end of the shafts...and when the spring rates go up, KATINK goes your shaft and KURPLOP goes a rocker and you're running on 7 now. Erson and Shelby make roller rocker shaft assemblies with a base design that uses a truss to grab the shaft at the very end, straddle mounting the end rockers and solving the shaft deflection problem....except for the taller LeMans valve covers you have to buy to clear those big locknuts. |
