In this episode Hal Fowler of Rottler Mfg and Chris Straub of Straub Technologies do a live demonstration of head surfacing. Then we head down to Creason Racing Engines in Troy, MO for insight into their head surfacing techniques before heading up to Larry’s Auto Machine in Croton, CT for a demo on block surfacing.

The surface machining session wraps up back in studio at Straub Technologies with a live Q&A session with Joe Creason of Creason’s Racing Engines and Ed Kiebler from Rottler.

Finally, the episode closes with a quick tech chip tutorial from Total Seal Piston Rings on why free gap in piston rings is so important in picking the correct ring material for your engine application.
