Cylinder Heads

Dan Simpson Engines has been supplying and fitting  aircooled VW cylinder heads made  by Mofoco in the USA for several years. Following a recent visit to their factory Dan is please to confirm that he has now been appointed the UK/Europe stockist for all things Mofoco.

Who is Mofoco?

Mofoco is a family run business in Milwaukee in the Mid-West on the banks of Lake Michigan, and the Henning family have been in business there since the 60’s. Randy Henning is now semi-retired although remains heavily involved in the business and owns and runs The Great Lakes Drag Way, a ¼ mile asphalt strip in Wisconsin. His two son’s Roy and Paul continue the good work he started in the VW scene. They produce a range of quality parts for aircooled VW engines and build to order several engines a week which they ship all over the USA.

Why Mofoco Aircooled VW Cylinder Heads

These American made aircooled VW cylinder heads are cast at a foundry just 75 miles from Mofoco using a superior quality material developed by the lads at Mofoco over many years. The castings are then machined at the factory using a blend of CNC and hand machining carried out by experts working at Mofoco. These aircooled VW cylinder heads have been developed solely by Mofoco over many years and are arguably the best VW air cooled cylinder heads on the market in the world today.

In independent testing, the Mofoco cylinder heads out flowed, out-performed and out cooled all other heads on the market at this time (CB declined to participate in testing).

Mofoco aircooled VW cylinder heads are not a production line head, once the castings arrive at Mofoco, they are part CNC and part hand machined by Dan, the head machinist, and his team at Mofoco. Dan lives and breath’s performance engines and machining, years of dedication and passion go into this process and he personally installs all the seats and guides by hand affording the correct press fit, unlike similar fitted on a production line using mechanical press. This guarantees neither will move or come loose, even under the hardest abuse. All 3 angle cuts on all the seats are also carried out by hand and finally every head is vacuum tested on completion. Before final assembly, he lubes all the valve stems, sets the springs to the correct installed height, then fits the retainers and collets. So, these are a one man, hand built, superior quality heads, produced with care and a multitude of experience.

Mofoco are also “Score” approved; this is an off road, desert, mechanically abusive race series, of the most demanding type. The participants will not accept head failures. M0f0c0 heads not only provide these racers with superior performance, they also give that oh so necessary reliability and exceptional cooling ability. The additional material in the plug areas and under the barrel seating surface, allows for machining for bigger barrels without break through and no plug thread cracking. To add to this, Mofoco heads have more and thicker cooling fins to give vastly improved heat dissipation and cooling, a must for all aircooled engines whether stock or performance.

The superior cooling and strength also allow’s for increased compression ratio, with no fear of detonation, thus promoting a more complete combustion burn, so less fuel is wasted, acceleration is improved, and flat spots eliminated. Only Mofoco heads can stand by these claims.

Mofoco cylinder heads are successfully being used on daily drivers, heavy campers pulling caravans, hot street motors, and race motors of all kinds and even twin plug aircraft engines, Even now they are developing an even better material for the castings, giving you the customer total peace of mind and assured quality.
