*UPDATE
Went to the machine shop today to talk to Bobby face to face to see what was up. He showed me all the heads. We looked at the 2nd head that was shaved for a 2mm hg (The one I bought from Patch!) That's the head I'm going with
I was worried about some pitting on the coolant passages but I brought my gasket with me. Bobby placed it on the head and used a pin to score where the piston walls would be. The do not conflict with anything. Bobby also measure the head from valve cover base to surface base, then compared to stock specs. He calculated out what my 2mm hg would be compared to the stock 1.37 hg and said it would almost zero out to stock ratios. Very close!
The warping on the top area was not as bad as he said it was on the phone. He showed me that they could correct it and straighten it out in the oven. I asked him what he recommended on doing and he said that straightening it really takes the integrity out of the aluminum and he recommended not doing that. He also said that he was seen way to many supra heads like this warping and it has never caused problems for folks unless they plan on pumping the boost in there like crazy! But I am not doing this with this rebuild so I'm all good!
So tomorrow they are going to start on a head job on that head and he is going to shave just a slight more off the surface to get it cleaned up more for my HKS MHG!
I am really relieved and excited about all this news today. Bobby was making it sound worse than it really was!
