Here's a shot of the engine bay as it exists this morning (June 2, 2021). Getting closer... I need to unbolt the exhaust up-pipe from the exhaust manifold and remove the steel fuel lines. There's still a fair amount of electrical and plumbing to get the left side clear enough to look like this side.
I know there's a grounding strap on the back of the driver's side head (left side) that'll need to be unbolted. And, I think I just need to remove the three bolts at the bottom of each exhaust up-pipe to then free the heads... If I'm missing something, let me know. The book says the turbo needs to be removed to do a head R&R, but it looks like I can get the intake Y-pipe unbolted without removing the turbo. Just need to remove the turbo compressor inlet elbow to allow access to the intake bolts... I think.
Getting the electrical connectors disconnected up to this point took quite some time... There are many different types used here, and each has its own enigmatic snap-lock design (plus needing to be very careful due to 20 year old hardened/fragile plastic). You can see the soot in the plastic coolant surge tank...
