OK here's the deal. I thought stock height was 116.00.I took my head in and they told me that it was below the minimum At 4.565 = 115.97mm But is .03mm below minimum? and it had a .010 = .27mm warp. Did they screw up? Or Am I missing something.
What's the stock head height?

Thanks ij I saw your thread and thats what i had though. Guess the guy at the shop doesn't know what he's talking about. You think they got it wrong at the shop? gonna call in the morning.

He didn't seem concerned about the the warp he may have switched from inches to mm on me. he said that the stock head is 4.74 = 120.40mm and that my head was way under the minimum at 4.565 = 115.97mm. I think he looked at the wrong specs.
No not for a 1jz. I am building a 7m.

I called them up, and they called to someone to double check their specs and they were told that IJ WAS RIGHT. Now I had taken them another head. they checked it and it was a full head 116.00mm, and had a .002in= .07mm warp. SO I'll be going with that head. The original head that i took them had a pretty good warp on it .010in = 0.27mm. They told me to strip it down all the way and then put the cams in and see if they turn freely. To see if the warp puts a bind on the cams. If it doesn't then take it back and the will resurface it. Does this sound right?
That all depends on the wear on the cams, more important is having them hardness test it BEFORE you spend another cent on it.
I haven't found a single machineshop in CO that has a hardness tester. Do I happen to keep calling super shitty machine shops, or is hardness testing not a common thing to do?

Reasonably cheap and while not super accurate is the bare minimum a shop doing Aluminium cylinder head should have and use.
Well the second head passed the pressure test and was resurfaced. the other still needs to be torn down. at least one of them was good. it was a junk yard find . well wish me luck on the rebuild of the head. thanks for the help.
