The sweet spot between horsepower and efficiency, Mofoco 042s are rated as the highest flowing as cast round port heads available.
VW cylinder heads are the best "bang for your buck" on increasing horsepower in your Volkswagen engine. This is because horsepower comes primarily from two things:
- the size of the engine itself
- and the air flow, port velocity and valve size of the heads
Engine size can't be changed without installing larger pistons and barrels or a stroker crank... but, new VW cylinder heads can be changed without splitting the engine case.
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.
