What I'm wrestling with right now is, should they be free-spinning (depends on if they'll hit the block) or indexed and solidly bolted on? I guess I can't answer that until I have it disassembled, with parts in hand.

"BUT, the problem also resides in hot/cool spots with operations vs. dummy cylinder areas. Coolant has a tough time regulating bores with no combustion and hot spots with where the action is conducted."
I don't believe you. Neither do any of the manufacturers that offer cylinder deac from the factory.

YOUR ECU screwed up because your "deactivated" cyls were still pumping air into the exhaust stream. John and I are talking about REAL deactivation -maybe ours should be called "decommissioning"- no air being pumped, no fuel being squirted, no pistons going up and down. O2 and ECU function should be "normal" then... unless the TPS being open wider throws something askew.

[1] Why would you want the extra weight spinning on the shaft?
wouldn't that create a parasitic load or even an off balance situation?
I would opt for a small core plug or maybe drive a solid pin all the way through.
[2] You don't believe the coolant would use the empty holes as heat sinks?
I read an old manual when I was in the Army, that gave instructions and part #'s for the conversion of 4cyl jeep into 2cyl run and 2cyl pump to build an air compressor.
Very neat idea. I am sure someone in the Pentagon thought about the heating and cooling factors.
[3] No extra air means the o2 reads right.
Have fun.S.
