Just finished up a template port for the world products Sportsman 2 heads. Wayy back I hand ported a few sets of these for superstock style drag race engines. These heads have great potential on 350-400” chev engines. And can out accelerate on track many bigger higher flowing heads. I have made 650+ real HP on 355” engines with this casting.
This is a mid size safe port with a 2.055 valve
Now to digitize it and create surfaces to get into production.
Fast hi quality cast iron heads are one of our speciality’s
