Dart Machinery SHP Series Heads
These cylinder heads are manufactured using a proprietary process employing permanent molds and a dense aluminum alloy.
New Dart SHP Series heads
Based on the popular 23° valve angle configuration, this cylinder head features a revised port design to deliver significant power improvements at budget-friendly affordability.
AFR Acquired by Private Equity
Air Flow Research (AFR), a manufacturer of high-performance cylinder heads, intake manifolds and related components, has been acquired by Taglich Private Equity (TPE) in a partnership with AFR’s founding family and management. The company’s 42 production and office employees based in Valencia, CA, will remain with the current executive team and staff. AFR was founded
Rechecking Valve Jobs
In this episode of Steve Tech, Steve Morris covers why it’s a good idea to always check the valve job on cylinder heads, even when they are brand new from the manufacturer.
Powerstroke Upgrades
Marketed as the ICON series, these cylinder heads are a totally new, built from the ground up, clean sheet, USA design that will replace Kill Devil Diesel’s previous aluminum heads for Powerstroke applications.
Piston Quench & Cylinder Head Chamber Mods
In this episode of Steve Tech, Steve Morris breaks down what piston quench is and what kind of quench is ideal, as well as certain chamber modifications you can make to get better performance in your engine.
Ultra-Smooth Surface Finishes
Determining the correct surface finish means you must consider the metallurgy of the head and block castings along with the type of head gasket you use.
Induction System Science
The complexity of cylinder head set up and flow bench testing comes in the form of math, aerodynamics, thermodynamics, and the physics it takes to design the correct port and manifold design for a particular engine combination. These processes take years to master.
Motorcycle Valve Seats
As it related to valve seats, it is important to know a bit about the different materials used and when and where it is appropriate to use them.
Hoops for High Horsepower
The hoop offers better sealing against exhaust gases because rather than the pressure trying to escape from a flat-on-flat surface, the hoop creates a lock between the head and the block to better seal the engine.
Cylinder Head Trends
Cylinder heads, as manufactured, are usually suboptimal due to design and manufacturing constraints. Porting the heads provides the finely detailed attention required to bring the engine to the highest level of efficiency.
Darin Morgan Joins BES Racing Engines
Longtime racing professional Darin Morgan has joined Guilford, IN-based BES Racing Engines. Starting March 1, Morgan will be responsible for assisting BES owner Tony Bischoff in several areas, including product development and cylinder head assembly. “I’ve known Darin for several years,” Bischoff said. “He has a great work ethic, plus, you can’t find many people
