Need a small block head guru PLEASE!!

Yes the heads and the block were "squared up" at the machine shop. After it was discovered to be leaking. The motor was pulled back out. :( Using a straight edge there is not anywhere that a .001 feeler gauge will go under. So we are thinking maybe just a faulty gasket. I hope that is all it is.

Thanks
I hope to know more in a week or so when the motor goes back in :(
