- 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 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.

Probably the most in depth type of technical podcast anybody can listen to. I listen to you guys during my lunch breaks and even before bedtime. Keep it up.
Clearly a clever and passionate bloke appears to be grateful of his terrific experience and is being generous with it
I cannot think of anyone with a better ability to clearly\simply restate someone's point than Andre does in these interviews. Amazing stuff...
Dave Localio and Darin Morgan are the 2 people I most want to have Andre do a postcast with. One down one to go!
Really enjoying this episode too, has had me frantically looking back at all of the work I had done on my heads and realising some 'mistakes' 🥴
Interesting interview, now I understand more what David was trying to point me out and guide my thoughts when I had my Cyl head build by him.
Been dying for this conversation.
I really wish headgames would have been around when my shop was open.... when I started we were one of the first shops that specialized in Subaru's and we were looking at what they were doing in the UK Japan or in Australia so back then it was a lot of trial and error and finding out what really worked in the real world and what was just talk .... I realize that now it seems that every shop works with Subarus but back in 2000 2001 we didnt even have the wrx over here so was a very different world and I only happen to learn and grow to fall in love with Subarus by taking a job as a young tech working at a Subaru dealership and being sent to training courses and the more I learned the more I admired..... but I was able to develop a very strong and dependable bottom end but I had to depend on outside shops when it came to cylinder head work and yes we made gains in power but never really what I felt was maximizing the head....idk
In my experience it seems like there are 2 main groups of thought when it comes to things like porting and air flow as it relates to power made by an engine..the air mass/volume camp and the air speed camp and I was in the air mass/volume camp until I worked at a vehicle OEM and got to work with one of the smartest people ive ever met in my life and all he did was port design and parts that need to have air flow (from the airbox all the way to the cylinder head ports) I learned more in a few months working on the flow bench with him and watching the things he was doing and I'm not afraid to ask questions and he was nice enough to answer them ...eventually lol but long story short I'll take fast moving air in a smaller port over a massive port that might have a good peak number but the air is incredibly lazy.....
So great to know that I can save hundreds on "upgrades" that are useless to my power goals. Thanks for the expert knowledge!
I don't understand any English, I have it with CZcams subtitles, but seeing that the podcast was with Dave I couldn't resist the temptation of reading it.
I’m an armchair engine builder at best.. I do enjoy cylinder head tech and porting information though, a fantastic podcast for me 👍🏻
Love the longer podcast. Great technical info in this one
This was a great interview, thanks again :) valve size info was extremely interesting
thanks HPA for that interview
Great stuff. I could have listened to another 1.5hrs
Very informative podcast from someone who really knows his business.
Love this, have been banging on about air velocity over flow for so long. Don't have nearly the experience but see the results for so much less money on the same Dyno but on the same platform.
Great insight into a man on top of his game.
Love the podcasts, hands down my favorite to listen too.
