Most would also assume that weвЂ™re going to spend a majority of our time on the intake side.

We also offer a few recommendations on how to perform those modifications.

What we deal with in this chapter is pointing out areas on a small-block Chevy head that respond the most to minor changes. As we learned in Chapter 3, good CFM combined with high velocity creates a very powerful cylinder head. On the contrary, itвЂ™s really more about removing only the material thatвЂ™s necessary to increase flow without increasing the overall size of the port. This chapter is not about hogging out ports and adding big valves. You just have to know a bit about airflow and where to spend your time with the grinder. Nevertheless, there is basic information out there for the taking that can and will lead to improved power and you can do it.

We donвЂ™t claim to be porting experts, because if we were, thereвЂ™s much better money to be made making horsepower for people than in sitting behind a computer putting words on a page. A step in the right direction is reading this book. As disconcerting as this may sound, the average enthusiast still has hope. The list of actual accomplished cylinder head porters who actually do know is far shorter. The point of this little rant is to introduce the concept that there are plenty of people out there who claim to know how to port cylinder heads. A head stand would also be a great addition to your tool collection. Find a spot on a workbench that can be easily cleaned of iron and/or aluminum filings.

Grinding on iron or aluminum heads is a messy proposition, so forget about doing it on the kitchen table.

By CNC porting the cylinder heads the high cost of hand porting is reduced, plus the CNC porting is more consistent and will produce better results. Hand porting is a very labor intensive and time-consuming procedure that takes years to perfect. The Lingenfelter CNC porting procedure is a computer controlled machining operation that duplicates exact details from a finished Lingenfelter hand ported cylinder head. Lingenfelter cylinder heads are precision CNC machined in house to insure that exact tolerances are maintained. This combination provides excellent horsepower gains while maintaining a strong torque curve. The port and chambers are carefully designed to provide the best combination of high flow capabilities and improved port velocity. Lingenfelter offers an excellent flowing CNC ported version of the GM 5.3 L aluminum cylinder head.
