VW Performance Heads

VW Performance Heads

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; - bigger is always more horsepower;
- and the air flow 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.

If splitting the engine case and all of the required machine work just isn't on your list of fun projects, nor is purchasing a stroker kit or a whole new engine for thousands of dollars... MOFOCO VW cylinder heads are a true bolt-on performance upgrade that anyone with basic mechanic skills can accomplish in a few hours. All Mofoco heads are made in the USA, too!

Details & specifications featured on all MOFOCO performance heads:

  • Approved for unleaded, plain old gas station fuel!
  • Heavy Duty Springs
  • Bolts right on in place of your old VW heads
  • Aircraft Casting Technology from a foundry in Manitowac, Wisconsin
  • Larger & Smoother Port Design for Better Air Flow
  • Thicker Port Walls & Larger Intake Face
  • 3/4 Inch Reach Spark Plugs
  • Silicon Brass Valve Guides
  • Three Angle Valve Job
  • More Cooling Fins than the competition - Thicker & Stronger
  • Thicker Combustion Chamber Ceiling
  • Standard 85.5/87mm Bore - larger sizes of 90/92mm & 94mm available
  • Machined on CNC-NC Milling Machines
  • Assembled by skilled artists & mechanics

Which head is right for you?

This question has as many answers as there are unique VW engine setups on earth... but as general guidelines, Mofoco recommends:

Mofoco 041 VW Head, the next step up from stock vw heads meant for engines up to 1679cc... these are for everyone looking for close to stock performance, while solving the infamous "bogging" issues caused by Volkswagen's original design, along with several other MOFOCO designed improvements, such as more & better placed cooling fins.

Mofoco 042 VW Head is made for literally any air cooled VW owner who wishes to have some extra horsepower in reserve, great cooling, and overall higher street performance... Hot VWs rated the Mofoco 042 as the highest flowing unported VW heads available! These will work on any size engine over 1600cc, however for the big and bad 2180cc or larger engines, Mofoco recommends...

...the Mofoco 050 High Performance VW Head! our self designed 050's were created with high horsepower, high capacity engines in mind. Featuring unique D-Shaped intake ports, these are frankly the most powerful street use VW heads on the market.

Quality takes time...

Mofoco performance VW heads are custom built to order! Manufacturing time is normally 1-2 weeks on standard performance heads. Sometimes, a customer ordered Mofoco heads, then later changed their mind, so we have Mofoco performance heads fully assembled & ready for next day shipment. Porting and polishing may take an additional one or two weeks if our metalworking artists have a lot of work ahead of your heads. If you have any special requests, please e-mail Mofoco's president, Roy Henning.
