Clean piston is often indicator where coolant was entering. Evaporating water blows away carbon deposits.

Yep
Getting the heads back Monday-ish.
I just picked up the cylinder heads from the machine shop. A respectable $177 and they did a great job. Cleaned, pump tested, replaced valve seals, surfaced, and lapped two valves.
And the mounting surface of the block. This surface looked like the one in the background. (EDIT: I cleaned the block surfaces, not machine shop)

Stoked for sure. Pulling the oil pan tonight to inspect the bottom end.

Beautiful
In due time. Summer is upon us.... and its gonna be hot!
Thanks Lee. Can we thank them for that? So far so good. But by golly, we needed three Japanese 9 year old girls remove the motor from the truck....
She sure is!
Some of today's progress
Chasing (re tapping/cleaning) the threads of the head bolt holes.
New head gasket
Installing the cams
And how I left it tonight....

I never sent the injectors in to be cleaned.... and I'm starting to run out of cash. So I'm taking a chance here and after lots of internet research, I'm going to attempt cleaning the injectors myself. I won't have any fancy flow ratings, but will have clean injectors none the less. Injectors are basically solenoids that open an close passing pressurized gas through a tiny valve. So I'm going to mimic the action by opening the solenoid manually, while allowing a pressurized solvent to flow through.
I've already cleaned my injectors in a ultrasonic cleaner filled with degreaser, shined them up nicely.
Here's the actuator rig I just finished building.
I still need to research the voltage that goes to the injector so that I don't burn it up. But basically, the plan is to connect to a small motorcycle battery and actuate the injector via tapping a momentary switch. I'll have another rig setup to flow the solvent and air. So far, my plan is to use about 12" of fuel line filled with carb cleaner (or denatured alcohol) then press the air nozzle into the hose applying the necessary PSI (yet to be determined), expelling any junk inside.

Just did a quick google search for What Voltage for Fuel Injectors and found this page... http://www.autodiagnosticsandpublishing.com/feature/fuel-injector-testing.htm
May be helpful for you. Seems very technical though. Not sure if you have an oscope at your disposal.

.... Actually........... I didn't think of that...
But, its a $4000 rig and I don't want to bring it home and dont want to clean injectors at work...
