I noticed my LS1 PCV hoses on the intake were getting pretty dryrotted and cracked. So I did the only logical thing, and decided to throw a host of things at the car. LS6 valley cover, removed the AIR system, new knocks sensor and harness, relocating a new oil pressure sensor, four port steam vents, plugs, wires, Holley valve covers w/ LS3 coils, Blackwing, and probably something else or two I'm forgetting
Anyways, I'm waiting on some parts, so here's a tore open top end. I'll post some more as I go. Besides re-taping some loose wire loom and general cleaning, anything I should aim to tackle while I'm this far in?
Valley cover installed and new knock sensors torqued to spec. Need to pop off the bottom driver side fender line to remove the AIR pump but that's tomorrow's problem. Rest of the parts arrive next week.
Which knock sensors did you go with? Only asking because in the last several years many [including myself] have replaced them "preemptively" and ended up with knock sensor faults. Many brands including AC Delco are triggering this issue.

I went with NAPA MPE DKS238SB after some research. QC on parts these days is rough. I'm honestly just hoping for the best lol I bought a new GM harness for them too.
Here is the oil pressure sensor relocation mocked up. Hopefully no leaks lol
Old spark plugs pulled, new TR55s installed and torqued to spec. Little bit of oil on every plug, with cylinder #8 having the "most." I may add a catch can to the project.
Pretty close to being done. Waiting on a other line to run the steam port to the radiator. I'll probably order a mighty mouse can too.
One small modification to the included coil bracket to use with the round LS3 coil and clear the alternator.
Does anyone see any issues with mounting my oil pressure sensor here? The hood closes, and I don't really know where else to hang it. I didn't want anything rubbing on the brake booster line.
Car is running, no leaks, no CELs - including none after removing the AIR system which I thought for sure would trigger a CEL. I did have an issue I'll cross post in Tech, but the car would not run with the LS3 coils. Terrible misfiring on multiple cylinders. Put the LS1 coils on, no issues. The steam vent kit was tapped right into the original throttle body coolant line on the radiator. Catch can is on.
