How to port-match LS cylinder heads for better flow! Turbo LS Caravan build #6

In this video, I disassemble the heads and then port-match the exhaust and intake ports. It takes a lot of patience, and you have to be careful not to damage the gasket mounting surface on the intake ports, or they could possibly leak. I didn't remove any material from inside the ports to make them bigger, simply made a smooth transition between the port and manifold.
