Wissota Superstock Heads

Our heads are designed for superior horsepower and reliability. We did extensive flow testing to develop our seat cutter design and valve back cutting angles to come up with our current combination. We use high quality parts to avoid engine failures. This also allows the heads to be freshened several times.

  • CNC machined seats with our own designed Wissota legal cutters for optimum flow
  • CNC angle milled and spot faced
  • Bronze wall guide lines installed (Superior lubricity and allows heads to be freshened several times)
  • Valves are back cut for better flow
  • New GM 492 castings
  • Ferrea 6000 series valves
    • Competition valves with higher fatigue resistance and tensile strength than our competitor’s best offering. These valves are made to withstand high spring pressure, roller and flat tappet cams, drag racing, oval track, road racing and sport compact.
