Haven't heard of "Heavy Duty Aluminum Push Rods" either.
Would like some more detailed info on them.
aircooled.net has them.
I’ve got an unused set in my stash, and I’m not surprised Pat uses them and recommends setting them to loose zero. Valve lash is a calibrated safety factor, meant as a “best guess” how much the engine will grow vs. grow much the pushrods will grow at operating temperature.
I have no experience with them, but my guess is that he knows they grow less than the engine.
