Sounds like burned pistons. Unfortunately I speak from experience. I had wet plugs and weird compression after some extreme tuning. Pulled the engine down and found all the pistons had some melting and on the worst (#4) the compression ring was on top of the piston. That's why I always have a spare engine.

Electrical, huh!!! You are getting spark, the only thing in question when do get the spark, “timing”, controlled by the ECU, crank sensor, location pick-up sensor, great mystery!!!!
You have everybody scratching their heads….
Please keep us posted; this is a new one on me!! (Thinking out side the box, “blocked intake port”????) Now that is way out their!!!
Good luck!!!

Well, I just got done talking to Rick and they figured out what's wrong.... #5 has bad piston rings. They scoped it and did a leak-down and all cylinders checked out except #5. It's not holding pressure and Rick said that they could hear air bleeding off into the crank case. The valves are fine. They're gonna pull the engine after they get done with another engine project and then I'll know the extent of the damage. Hopefully it just needs new rings and that's it. But if the block needs to be re-honed, Rick has a good engine guy in Atlanta that will take care of it.
This sucks, but at least now I know what the problem is...

Sorry to hear it T at least it's the right time of year to be down
Rings are a funny thing and until you see exactly what happen it's going to be a mistery. JDM builds amazing motors and you as said you got years of fun out of it, once you get a better look at it hopefully you'll have your answers and an inexpensive fix
BEST OF LUCK PAL
