Editing Porting cylinder heads

== PREAMBLE ==

The purpose of this article is to acquaint engine builders on the tangible benefits of cylinder head porting and making more power through the porting process. Cylinder head porting or 'porting' as it is known in the hot rod circles, is classed as '''black magic''' in the engine building process. Proper porting procedures will result in getting the largest volume of air/fuel mix to the combustion chamber in the shortest amount of time. Porting works hand in hand with valve grinding and seat cutting.

== Step by Step Porting Methods ==

Before you go out and grab your tools and start grinding on those $1000 Edelbrock heads you just bought, STOP. Porting requires practice, so do exactly that, practice on a set of old non-descript heads that you picked up at the local auto recycler. Try out your tools and see what they do. Remember to use the correct tool for cast and aluminum heads so you do not ruin the tool and hurt yourself. After you feel confident with working with your tools, we will go on to explaining what we want to accomplish in each segment.
