Our 223cc CNC'd head based on Dart's aftermarket castings is a great budget option for those who want to stick with cathedral heads, but don't own GM 243's as a base for our work.  They feature lightweight stainless steel valves with 2.00/1.575" head diameters to maximize available piston to valve clearance (Approximately stock GM 243 P2V at 63cc).  Like most aftermarket casting based heads, full bronze guides are a standard feature.  More info & photos will be added soon.  Thanks!
