You cannot set the lash using a feeler gauge with a solid lifter camshaft if you have self aligning rockers. The gauge will not fit between the rocker and the valve tip.
Self aligning rockers are difficult to use with Comp Cams 875 or 15850 short travel hydraulic lifters. Those lifters set a .005" pre-load. I am using CC 15850 lifters and can set them with a "flick of the wrist" without a feeler gauge which is 1/16" to 1/8" pre-load.
just cut the tip of your feeler gauges down... a set is like $5?
