077: Art or Science? Head Porting Explained. [PODCAST]

How useful are flow bench numbers? Should we be mirror-finish polishing our ports? What about adding dimples like a golf ball? On this episode of the podcast, David Localio of Headgames Motorworks joins us to dive deep into one of the most misunderstood areas of the performance automotive world — cylinder heads.

David Localio of Headgames Motorworks is best known for building and developing some of the fastest import cylinder heads anywhere in the world. He’s able to do this thanks to two decades worth of experience in the game, as well as a healthy passion for making anything on four wheels go faster.

We first learn about David’s early years, in which he saved up his paper run money to buy his first muscle car at 12 years old (then subsequently got that car taken off him after driving it around the neighbourhood one too many times), then jumping into the street racing world before eventually finding his true passion through both an education and hands-on experience at some renowned engine building shops.

After soaking up all that knowledge, David then started New Jersey-based Headgames Motorworks, where he continues to hone his craft, all while building heads for some of the best-known and decorated import cars in the world.

Head porting is an area that seems to suffer — or benefit, depending on how you look at it — from a crossover between science and art, so much of this conversation is spent getting into the finer details of many aspects of head work, from port and polishing, to valve grinding, cam selection, and much more.

David has some very interesting non-conventional views on what works well and what doesn’t when it comes to headwork, and while any ordinary person might have those controversial opinions dismissed by the masses, this is a guy with the results, the records, and the trophies to back it all up. This is one episode of Tuned In NOT to be missed.
