Remember that's .001" over about 16". If you can hold that with a mill you're doing pretty good. Generally straight edges are ground because it's more precise.

How do you usually hold anything to the table of the surface grinder? You need a magnetic chuck. Also, aren't most ground precison straight edges usually accurate to one or two tenths per foot? A straightedge accurate to .001/ft isn't going to tell you if that yota head is out .002 at 16", which is it's limit. Even cold rolled stock is accurate to a thou per foot, isn't it?
well we have a magnetic chuck, but you have to use a small vise on the table and back it up,i don't have a way to hold it to the table on edge. our machine is ancient, it's a wierd one instead of the head moving,the table goes up and down and the head is stationary. i think he needs to take it to a shop anyway, it would take no time to check it for warpage. because it may have overheated he really needs to take the head apart and have a dye penetrant test done in case it has any hairline cracks in it. i wish he lived out here i could help him more. he said there are no machine shops there,but i googled ridgecrest and there are a number of them right near him . complete with directions and phone numbers. i told him to call them and at least talk to some of them,find out what they say. so far he hasn't.
I wouldn't surface grind it anyway but its a nice offer. Most surface grinders the table moves not the wheel it what keeps it accurate. Even then the set up would be tuff since the face need to be up getting it dialed in be a PIA.
fly cut a head might be 35$ maybe 50$ one pass. For all this he could have had it done already.
Just for yourself could try to fly cut it on a mill but the setup would be too tricky to justify the cost.

i could do it for him,but the shipping alone would be twice what a machine shop would charge. i could shim it on the table and indicate it so the four corners are the same then flycut it,but not worth the cost. when i did my manifold for the Su's it was even a pain to do.
and cah the transmission goes in from the bottom up,not the other way around.
