Valve Job, Milling & Assembly | Lamborghini Huracán Head Build (Part 3)

In Part 3 of our Lamborghini Huracan cylinder head series, we dig into the myth that “bigger valves make more power.” Spoiler: they don’t fit — and the only valves most companies offer are actually Gallardo pieces… including oversized exhaust valves that DO NOT belong in a Huracan head. In this video, I show you why the Huracan platform doesn’t accept larger valves, why mixing Gallardo valvetrain components creates geometry issues, and how the GSC Power Division spring package fixes the weaknesses in every other option on the market. We mill the Huracan head, show the interference points, compare valve sizes, spring pressures, and finish with the completed heads ready for assembly. This clears up the confusion, saves builders money, and helps Huracan owners avoid catastrophic mistakes.
