Mofoco 042 Cylinder Heads Updated ports,casting Price: $299
Featuring 40mm stainless steel intake valves and 35.5mm stainless steel exhaust valves, 042s are the sweet spot between horsepower and efficiency on vw engines from 1600cc to 1914cc.
After 20+ years of success, the 042's have been upgraded for more flow as cast, no step 55cc combustion chambers for maximum quench, more airflow through the head for maximum cooling, added material so boring for 94mm cylinders won't break through to the fins and now come standard with chromoly retainers. With the intake port volume at 62cc, the port velocity is perfect for a street performance cylinder head.
