Digitizing & CNC Porting the BMW B58

Part 2 of the B58 trilogy shows the entire digitizing and CNC workflow at HeadGames Motorworks. Matt and Dave break down probing, collision geometry, surfacing, port mapping, fixture strategy, and then cutting the final geometry born from Part 1’s hand port. You’ll see: – Digitizing the hand-ported runner – Building the CNC model – Collision-avoidance geometry – Test cuts – Full CNC porting of the intake & exhaust – Side-by-side comparisons with stock
