Machine shop got back to me on the head, one burned exhaust valve. They say they can get an SBI valve. Should I go with that or order an OEM?

Will you be able to sleep at night knowing what you did? My conscience would weigh too heavy on me if I had one valve different and non-OEM from the others.

True.
 
**Edit

One of the valve guides needs to be knurled so I ordered 12 new replacement guides as well as a new exhaust valve from Toyota.

After scratching my head the past few days, I think I have my add on circuits mapped out. I want to utilize the available space in the factory box. With the ABS out, I will use that feed for the york and the aux fan and replace the 60 amp ABS fuse with a 30 for the compressor. While at the moment I have the fan drawn up using a stand alone OEM high amp toggle switch, I might utilize the OEM fan relay blank to use a standard pushbutton.

The fog lights I don't have will get to use a blank pin crimp on the fuse bridge between the left and right headlamp fuses. If I have read the diagrams correctly, this will allow them to auto shut off with the door switch like the headlamps. An OEM high amp fog light switch will be used. The DRL'S will share the crimp on the EFI ACC side of the relay.

I believe I have this sorted correctly. Here is the sketch I made. Please yell at me if something is incorrect/bad.

Removed my Chinese 10" fan and installed a 12" USA made Flex-a-lite fan.

Cut out over 25ft of the DRL harness wiring crammed into the engine bay and will use this spot as the ground location for the front accessories.

I believe a AC clutch takes only around 5 to 7 amps with a momentary spike during engagement.
 
I mean for the york clutch.
Ah, lol. Thanks. I was just mimicking the fuse layout that came with the wits' end manifold, it is 30amps.

Good info though, as it gives me a better idea of the available amps on the ABS circuit. Thank you.
 
Some parts came in but still waiting for my fuse terminals and power wires.

Three grounds have been ran for the in-cab switches. Seat heater switch for the York relay and the two OEM toggle switches for the fan and fog lamps.

Finished installing the wits' end air manifold kit and running the wires for the relay and power supply. The power wires follow the same path as the air line I ran.

Pulled the outbound side of the ABS fuse and attached it for the York compressor.

Scored another free power supply and switch for my under-hood lighting. This removes yet another wire I had running to the battery! The relay that comes with the air manifold kit has an unused power wire (87A). This circuit will always have 12v until the relay is energized for the York, perfect. I added my previously unused wits' end fuse terminal to 87A, then to the switch normally used for the York compressor. (This is not in use since I am installing the in-cap switch.)

Once I finish cleaning the hood and restoring the hood ribs with seam sealer, I will run the power to my light.

This is the 12v supply/fuse terminal bridge for the headlamps. The empty spot is where I mentioned I will crimp my supply wire for the fog lamp circuit.

I also removed yet another wire from under the hood. It was used for my subwoofer amp (8awg). I will instead run 4awg Monster cable to a distribution block in the back. This replaces my old CCA 4awg jumper cable wire I stupidly used for the fridge and Puma prior. This Monster cable used to power my subs I had in my totalled GMC Sierra.

FINALLY, 24 new valve guide bushings.

20210911_161917.jpg
 
Intake valve guide bushings were fine so just the 12 exhaust bushings were replaced along with the one new oem exhaust valve.

Head was off .006 so they surfaced that, new intake and exhaust valve stem seals, pressure tested, polished the cams, full valve grind with tipping the stems and setting the adjustments, tanked the valve cover and intake manifold.
