* Direct replacement from the stock hydraulic lifters. Adjusted by shims. * Requires solid type camshafts. Small base circle diam:φ29 * Suited for TOMEI camshafts with cam lift greater than 9.25mm or 10.25mm * High strength by cold forging, lightweight.
Most cams have .010 to .020" quieting ramps, that means you have ~.035" too much clearance when hot with solid lifters. The height of the quieting ramps is why cams are spec'd at .050" lift instead of when the lifter first starts moving. Compression has nothing to do with valve adjustments however the cam profile has a large influence.
