I have done this in a very similar way using a pane of thick glass and it does work but you will be getting a real upper body workout! I still like having a machine shop do the job, the machining marks help seal the head to gasket surface better, imho. Generally, when an aluminum head warps, I just replace it with a new one, they are cheap enough for most vehicles I have worked on and you get nice clean oil and water passages as a result. But, if you are on a tight budget then yes, this manual way works.

He forgot to mention how to line bore the cam bearings after you sand the warped head. Been there, done that, broke two cams before I figured that one out. Now line boring(OK. actually sanding) the cam bearings while still on the engine was a trick. But it left the driveway running.

You are so correct, ws27. I wonder if the dude in the video knew about that requirement? LOL. Been there as well, thats' why I just replace the head with a new one. Autowrecker aluminum heads are a nightmare at the best of times and mostly not any better than the head needing replacing. Main cause of head warpage??? Lack of coolant due to a rad or waterpump leak, in my experience. Secondly, lack of oil from a burner engine or leaky engine. 3rd, improper head torquing sequence. Planing also increases the compression ratio slightly.
