Not quite... Ignition timing (aka spark advance) is controlled by a number of factors and is completely dependent on a cam position sensor. In the GTE the CPS is all there is as the ECU provides the spark through additional circuitry... in the GE there is still a CPS (it's in the base of the distributor and actually you can use a GE's distributor as a CPS in a GTE in an emergency
) and the ECU still regulates the spark.

Umm.... well, I might be able to actually. Do you have the part number for the plugs you installed? The listed replacement plugs for our car made by autolite have a shorter insulator (approx 1/8") and as a result often have misfire issues. I strongly recommend replacing the plugs with some of the specified NGKs. If you go with another brand compare them VERY closely to an OEM specified plug.
Did you retap for the new helicoils (eeek)? How did you keep the cylinder clean?
EDIT: also, I recommend replacing all of your plugs at the same time. Mismatched plugs can cause issues with diagnosing misfire problems and make it difficult to read the spark plugs for indications of engine problems and to put a time to the start of those problems.
