​'BETTER THAN BILLET ' RECAST CYLINDER HEADS

• WE ONLY CAST OUR HEADS FROM A HIGHLY ENGINEERED MATERIAL CALLED COMPACTED GRAPHITE IRON

• WHY CGI?
  

1. CGI HAS 4 TIMES THE CRACK RESISTANCE OF ALLOYED GRAY IRON: BENEFIT = RESISTANCE TO LOW CYCLE FATIGUE
   
2. CGI HAS 3 TIMES THE DAMPING CAPACITY OF DUCTILE IRON: BENEFIT = IMPROVED COMBUSTION AND LESS VIBRATION TRANSFER TO FUEL INJECTORS
   
3. CGI IS THERMALLY MORE STABLE THAN DUCTILE IRON AND STEEL: BENEFIT = BACK TO BACK PULLS ARE A NON-ISSUE
   
4. ​CGI HAS A 20% INCREASE IN MICRO HARDNESS OVER DUCTILE IRON AND 50% OVER STEEL: BENEFIT = BEST IN CLASS VALVE SEAT WEAR RESISTANCE AND NO DEFORMATION TO FIRE DECK DUE TO FIRE RINGS
