IronHead research

The research arm behind the IronHead guide catalog. Each published guide is the end of a sourcing-and-scoring pipeline — here you can read the shortlist of candidate models the team is evaluating next, and the rubric that decides which ones make the cut and how the published guides stay accurate over time.

Latest analyses

Scoring rubric

How a model is scored.

Documentation depth, restoration frequency, parts availability, and coverage gap folded into a single four-axis rubric — the standard every candidate shortlist entry has to clear before the research team commits five months of source work.

Model evaluations

Model evaluations in the catalog.

Every published guide in the catalog is the end-state of the same sourcing-and- scoring pipeline — a 30+ page restoration doc you can read end to end is the artifact the research team ships once a candidate model clears the shortlist rubric.
