Ok just re read the thread. Liner protrusion is critical to head gasket welfare. Even if it’s in spec and you don’t pull the liners, use a stud kit, not head bolts. Not sure if you can get an accurate measurement on deck condition with liners in the block. These blocks can warp after overheating and head gaskets will not usually survive until recitified. Studs will give you sustainable tension.
That polished spot on one of the bores, is it #4 or #5 or between that Siamese point? Because that is where all these blocks crack behind the liners when properly overheated. Between 4&5.
Given the condition of the head gasket, poor honing, mismatched part installation, possibly cyl #4/5 have polish marks on bore, and harmonic balancer issue, you might have an engine that’s been slapped together for a quick disposal.
I’d pay close attention to block deck condition, liner protrusion and especially size all the liner bores. This will determine if you should strip the block and go the full monty.
If there’s an issue where that polish bore mark is, it may be in the parent bore behind the liner. However alternatively if that odd piston/gudgeon was in that bore, it may be piston slap induced by poor balancing that caused that polished mark. You really need someone to inspect and give a secon opinion because some things just aren’t adding up.
