The second and final phase of typical development to improve flow over standard.
In part 1, I carried out a series of preliminary tests, basic modifications and flowtests to establish the potential of the inlet port on the Fiat TC 1592cc cylinder head - things like testing the bare port flow and manifold flow, improvement to the short side radius, opening out to valve correct seat diameter, opening out the valve throat. In this section we'll see how these steps are taken further and how the port - chamber region of the inlet side is fully developed and checked ready for building-up.
