Degree wheel

Long travel dial indicator ( for measuring stroke and index)

normal dial indicator (for valve events)

piston stop--heavy bridge across cyl with bolt

plot out all timing events, piston stroke, piston to deck --then you can know if crank is off, cam is off ---you can compare #4 to #1, #2-#3

A distributor machine can be used to check you 1-4 timing ---just because it is electronic doesn't mean it is correct. ---and it can verify your advance curve.

Have you tried sourcing rods from a different place?

Both #4, and #1 should show the same when using a timing light

A 4cyl crank can also be checked with V blocks , a height gauge on a surface plate -set it up, flip it over, check again.

Is the same rod being rebabbitted again and again, or is a different rod core being used?
