That depends on the cam. If it's hydraulic there would be preload, not clearance. If it's solid, you'd need the manufacturer's cam card to set the correct backlash.
To convert your 1971 Olds 350 Rocket to a full roller rocker setup, you'll need to replace the stock rocker arms with roller rocker arms. Make sure to select a compatible ratio (typically 1.5:1 or 1.6:1) for your engine's performance goals. Additionally, check for proper valve clearance and possibly upgrade the pushrods if necessary. Finally, ensure all components are installed correctly and properly adjusted to optimize performance.
To convert your 1971 Olds 350 Rocket to a full roller rocker setup, you'll need to replace the stock rocker arms with full roller rockers designed for your engine. Start by removing the valve covers and rocker arms, then install the new roller rockers, ensuring proper alignment and clearance with the pushrods and valves. It's also advisable to use compatible pushrods and check the geometry to ensure optimal performance. Finally, reassemble everything, double-checking torque specifications, and adjust the valve lash as necessary.
If it has center hold-downs on the rocker covers, it's probably a roller cam.
No, It does not change the ratio of the rocker arm. ( lift or duraration ) They are designed to keep from cutting into the rocker arm stud if you have a 500 lift or more camshaft that's it.

To set the valve clearance on a Yamaha Big Bear 350, first, ensure the engine is cold and then remove the valve cover. Rotate the engine to set the piston at top dead center (TDC) on the compression stroke for the cylinder you are adjusting. Use a feeler gauge to measure the clearance between the valve stem and the rocker arm, adjusting the clearance by loosening the lock nut and turning the adjustment screw as needed. Finally, recheck the clearance and reassemble the valve cover.
NO. The 86 is not a roller block.
No it will not, not even close.
