David Vizard's How to Port & Flow Test Cylinder Heads

Porting heads is an art and science. It takes a craftsman's touch to shape the surfaces of the head for the optimal flow characteristics and the best performance.
Porting demands the right tools, skills, and application of knowledge. Few other engine builders have the same level of knowledge and skill porting engine heads as David Vizard.

All the aspects of porting stock as well as aftermarket heads in aluminum and cast-iron constructions are covered. Vizard goes into great depth and detail on porting aftermarket heads.

Starting with the basic techniques up to more advanced techniques, you are shown how to port iron and aluminum heads as well as benefits of hand and CNC porting.
You are also shown how to build a high-quality flow bench at home so you can test your work and obtain professional results. Vizard shows how to optimize flow paths through the heads, past the valves, and into the combustion chamber.

The book covers blending the bowls, a basic porting procedure, and also covers pocket porting, porting the intake runners, and many advanced procedures. These advanced procedures include unshrouding valves, porting a shortside turn from the floor of the port down toward the valve seat, and developing the ideal port area and angle. All of these changes combine to produce optimal flow velocity through the engine for maximum power.

Practical Gas Flow - Techniques for low budget performance tuning

Back in print and completely updated to cover more recent engines and taking into account new emission control laws, etc.
For the do-it-yourself tuner intent on increasing the power output of a car engine, no problem is greater than how to measure, assess and understand the flow of gases through the inlet tract, clylinder head and exhaust.

Gas flow, complex, variable and invisible, is the key to an engine's performance, and professionals use very costly equipment for its investigation.

This book describes a practical low-cost alternative that lets you check the gas flow in your engine, devise improvements and test and compare their effect: it needs patience, persistence and some manual skills, but no great financial outlay.

Praxishandbuch Nockenwellen - Verstehen, Pflegen, Optimieren

How sharp can it be? Anyone who prepares an engine - whether to seriously tune it or simply to get the best out of the standard machine - cannot avoid the subject of valve control. The pivotal point in the four-stroke engine is the camshaft. They are available from mild to sharp, from brand new to reconditioned.

Des Hammill, engineer and experienced professional racing engine builder, knows what is important. In this practical manual from the Oldtimer Markt edition, he reveals how to find the right shaft, how to set up the control correctly and how to test it.
If your engine still doesn't run after tuning despite following the tips in this book, then it is definitely not the camshaft.

Praxishandbuch Zylinderköpfe

When it comes to increasing the performance of four-stroke engines, the first thing that comes to mind is the cylinder head(s). This is where the mixture supplied by the carburetor or injection is converted into pure horsepower.
Understanding the functional relationships of the individual components of the cylinder head is the key to high performance, reliability and economy of every four-stroke engine, both in road use and for use in motorsport.

This volume of the Praxishandbuch series describes in great detail and with the help of numerous pictures and illustrations, first the theoretical basics of cylinder head technology and then explains possible steps for increasing performance. All components are examined separately - from the inlet and mixture formation, through ignition to the outlet and exhaust system.
Written in an easy-to-understand manner and carefully compiled, this book offers the technically interested reader everything they need to know in order to be able to carry out work on the cylinder head successfully.
