Can this be used on all Chevrolet models from 1955 to 1986?

Yes, it is compatible with all Chevrolet models from that range.

Why is push rod length important?

Proper push rod length is crucial for peak engine performance and to avoid mechanical issues.

How is it possible to get a proper reading when checking the valves on a LS1 engine without applying the proper preload on the lifters?

The tool is to check the length of the push rod needed when the rod is just touching the plunger of the lifter. No preload or 0 lash. Work well with a push rod length checking tool. Check Summit comp cams part #7702-1. Make sure you buy tools for LS since other gm engines may take different tool.

Do u still need to remove heavy springs and turn over the engine still using this or does it allow u to skip all that and just set it on and check?

This is for checking pushrod length on a disassembled valve train. The only thing on the head should be the stud for the rocker arm and the pushrod sitting in the block.

Will work for 1.6 rockers?

It’s for checking pushrod length. Sure.
