Just be careful if you get close to the transmission kick down cable when re-installing the wires. I pushed on mine a little and the plastic part that goes in the transmission blew apart.
 
I'd scrub it some more with red scotch pads and a lubricant of your choice. Just grab a beer, sit inside the bay and just scrub away. It's therapeutic, and you'll have solved a lot of personal problems in no time. If you can purchase/borrow a machinist straight edge, perform a check using the FSM with a feeler gauge.

Have you ever tried a granite surface plate and light grit sand paper and you just use the weight of the slab and drag it back and fourth till the block is adequate, although you certainly want to stuff oily rags into the piston holes to catch debris. Obviously check afterwards with a straight edge just for hehe’s

Thanks for the suggestion, I ended up getting it cleaner with pics that I posted afterwards. Its as clean as can be without risking the straightness of the block.
 
I'm sorry if this was already asked, I think I read through a bunch of the head gasket installs to include Otramms excellent video, but what would be the difference in the subcomponents installed on the head prior to installing it on the block if this were in vehicle vice removing the engine? I'm considering PHH, EGR piping, but worried the lower intake plenum will make fishing the over transmission harness connections really difficult. Could I take the lower plenum and snake the harness through the hole and then leave the plenum loosely laying over the head resting on some cardboard. Then snake the transmission connections through to include all of the harder to reach stuff. And finally attach the lower plenum albeit with some difficulty reaching the most rear bolts and nuts? Any issue with this?
 
There is a modification to the lower intake manifold, cutting out one of the supports where the wiring harness passes allowing easy removal of the harness. Can't find a thread but maybe someone else will comment.
 
Can anyone tell me what this might be? Or possibly what stock harness pigtails the PO used? Relay is for relatively high 40/30A on passenger side near firewall on 96’ LX450.
