I measure .006 warpage right at the cats torso between the cylinders. Of course this is with my jank **** square. It will hopefully be going to the machine shop tomorrow and hopefully within the week be complaining about how much it costs to check and to shave off a few thou.

actually I was jus gonna glue some sand paper to the sidewalk and rub the head around on it and finish it up with my harbor freight belt sander.
40-60 is really reasonable I am down with that!
The shop I use has all the proper equipment. I would never use a shop that uses a belt sander to surface a head!
They even got this dope crank balancing setup.

Well I doubt these updates are very interesting but hopefully posterity will find them useful.
The machine shop says a .008 straight razor shave will fill the bill. They were also concerned with the indentions around the chambers. I noticed this as well. There were lines around the chambers I guess from sealing ring of the gasket that got pressed into the head. They were smooth but could be felt with the finger nail. It wasn't all around the chambers just in spots.
I would take a photo but I doubt it would be visible. The moral of this fairy tale is if your head isn't smooth and flat for whatever reason you are gonna have a bad time.

Sure the guy might sand away the marks and stains from the gasket but how does he know its square to the rest of the head? Also just because he uses a ruler doesn't mean his ruler has any kind of accuracy he might be close but from what I understand a MLS sealing surface needs to be within .002"
I do give him credit he thought things through at least by mounting the sand paper on a board he checked with is ruler and knows how to check a head for flatness but its his ruler thats his problem and his false economy of doing it himself rather than paying a machine shop to do it.
