The PO said they did not resurface the Head becasue it was within spec.
Apparently Hunter PMed and ask if the sand Blasted the Head; I guess meaning the part of the Head the Head Gasket Seats on.
I am curious to see what the answer is as I have not worked any place where the sandbasted the Deck of the Head. That was done when needed with wet/Dry Sand Paper and a flat Block.
Also some shops have Basters that use coarse media (OK for Exhaust Manifolds or the exterior parts) and other have Blasters that use Glass Bead Media.
Every Place I worked they used glass Bead Media.
It has not been mentioned but once in a while the top surface of the Block is warped. Most People don't have a precision staight Edge at home to check the surface of the Block and you cannot always get away with not checking it.
It has not been mentioned if that was checked or not and the condition of the surface has not been mentioned.
I know on Gasser Engines you need to be carful to clean the crud out of the Bottom of the Head Bolt Holes and chase the Threads and use the proper lube so you don't get a false torque on them.
I have been I have only had a few Engines that needed the Head Bolts or Nuts tightend to some angle after torqueing them.
