VK56 Head Disaster to Redemption | Flow Testing, Pocket Port & Full Build

Things don’t always go to plan at HeadGames. We set out to build Jon Rogers’ VK56 head — but cracked it pressing in new guides. Instead of hiding it, we tell the story. Jon sent us another set of heads, and this time we went all in: flow testing before and after, a fresh pocket port, bronze guides, valve job, lash setup, milling, and full assembly. The big question — does our pocket port + valve job combo actually out-flow the hand-ported head Jon sent us? Watch the full process to find out. HeadGames isn’t about excuses — it’s about results. This is the VK56 head story, start to finish. Part 1 https://www.youtube.com/watch?v=1jptPFI85gk
