The W58 had round ports...




I did this once by removing the valves and used a chisel to slit the liner in 3-4 places and twist the pieces out. First one took 45 min the last one 15. The ports also have raised bumps, (you can almost make them out) to keep the metal away from the port walls which would cool them too much. The idea is for the liners to glow hot enough to burn off any hydrocarbons.

I guess that makes sense, just looked at some pics I had of my motor and it looks like the manifold is a tube and not square.
