Cylinder Head Porting

All of our Head Gas Flowing is done in house using the best porting equipment on the market. Gas flowing is an art and takes a long time to master. A lot of time and effort/development work goes into perfecting each cylinder head. We test each cylinder head on our superflow flowbench to maximise performance. 

 

Send your head to us to have the inlet and exhaust ports flowed. Gas flowing/Porting helps the engine breath far better by allowing the fuel mix to enter and exit the combustion chamber at a faster rate, it also helps the fuel mix atomize to create a much improved combustion. Most cylinder heads can be improved drastically with port work purely because the ports are so poorly designed along with poor casting. All of our cylinder heads are flowed to give a great overall power increase. We offer a range of cylinder head packages, we can also replace valve seats, stems and repair any damage such as worn followers.

 

We also have many CNC cylinder head specs available, we can custom design new head specs to suit your  build.
