Cylinder head porting requires more specific tools and now we will continue to review them so people can learn what tools we use.
What we need after the cutting section are some grinding stones and polish assortment kits. These come in different shapes and like the cutters we use various shapes to help us shape and contour the ports better and here are what they look like.

Now its the time to start reviewing the special tools we use to make winning heads. Of all the tools that we use the most import one for cylinder head porting is the Flowbench. The flowbech is used so we can measure the actual amount of airflow that is flowing inside the ports and without it you can not know if a certain modification done on the port will result in an improvement or not and finally into actual power increase.
Flowbenches can be bought in various sizes and also if one wishes and wants to save some money can even build one himself. There are alot of DIY flowbenches out there and if one wishes to go that way please let me know. For myself I use a Superflow flowbench which is a great piece of equipment and is calibrated and I can check and compare my results with others too.
A flow bench can flow in either direction, that is intake and exhaust and with other special attachments, operators can determine the flow direction traveling into the cylinder so they can optimise the air/fuel mixture.
I would also like to point out on some great books on this subject and a definite buy for the serious enthusiat wishing to have more knowledge and start porting his own heads.
