You will not be able to get a feeler gauge between lifter and valve as the lifters are spring loaded upward.

With the noise quieting with increasing temperature I would rather suspect piston slap or a wrist pin knock. Test for that by shorting cylinders one at a time while the noise is present and listen for a change.

You also might want to lay a stethescope on the fuel pump.
