Complete timing set installed. Will edit this post with some pictures eventually.
Quick tip, don't forget to tighten the lower oil suction tube bolt before you install the timing chain, lol. It is behind the chain so really tough to get to if everything is already installed. I ended up removing the tensioner and one of the guides in order to get back to it.

This video will save someone a bunch of time or even the cost of a new tensioner if they thought it couldn't be reset. I imagine this to be a common problem because as everything goes together it is easy for the tensioner to need to be adjusted. If the chain slips while the tensioner is being deployed it may need to be reset for a second attempt at install.
I spent a few minutes struggling with it before I saw this video and realized that it needed to be pressed back beyond flush in order to get it to reset. It is pretty simple to press it down on a small socket or something else of small diameter. Once depressed beyond flush the lock pin can be replaced and it is ready to go for a second attempt.

Last night:
- Exhaust reconnected to manifolds
- 02 sensor plug heat Shields re installed, these are a bear to reach due to their location
- Starter reinstalled
- Completed timing procedure by rolling forward several turns clockwise and attempting to replace the Cam alignment tool which dropped right in, so supposedly that means timing procedure was effective.
tip: The book procedure uses the main camshaft bolt to turn the engine clockwise. This is complicated by the fact that the threads are left handed so the bolt must be torqued counter clockwise before you can use it to turn the engine clockwise. They do this by having you remove the starter and install a locking tool allowing you to achieve 50 ft-pounds of torque in the counter clockwise direction without rotating the timing chains counter clockwise. This is very labor intensive especially if you don't have a lift to get underneath the vehicle.
I found that by lightly installing the crank dampener pulley you can turn the engine clockwise by hand. If the engine is a little tight or you are just a weak person, you can use a T50 torque bit in the smaller bolts on the crank dampener to get your clockwise turn since these are normal right handed threads. This would have saved me a bundle of time to begin with as removing and reinstalling the starter in cramped quarters absolutely took too much time.
