In one of the last roundtable discussions of the 2022 Expo, Joe and Lake are joined by John Callies, Mark from Brodix, Vic Hill, and Donny and Jaden from Straub Technologies to talk cylinder heads.
In an entertaining and informative session, the guys talk about the “voodoo” behind head porting, the benefits of new technology, and why some things are still done the old school way.
There’s also plenty of stories about cylinder head development (some would call it “testing the limits of the rules”), why everyone switched from cast iron to aluminum, and the crazy things some engine builders do in a search for more power.
Following the roundtable, John Callies closes the episode with a Tech Chip tutorial on valvetrain surface finish – roller finish vs camshaft finish.
